Fast forward and rewind button (SwiftUI)

So I am trying to add two buttons to the view of my SwiftUI app that will allow a user to fast forward and rewind the audio clip.

I already have it working on the Lock Screen and notification bar, but in the app I can't figure out how to link two buttons to these actions.

I am wondering if anyone is able to assist.

In the MusicCore.swift I have the following

func setupRemoteTransportControls() {
   // Get the shared MPRemoteCommandCenter
    let commandCenter = MPRemoteCommandCenter.shared()

    let changePlaybackPositionCommand = commandCenter.changePlaybackPositionCommand
    changePlaybackPositionCommand.isEnabled = true
    changePlaybackPositionCommand.addTarget { event in
            let seconds = (event as? MPChangePlaybackPositionCommandEvent)?.positionTime ?? 0
            let time = CMTime(seconds: seconds, preferredTimescale: 1)
            self.player?.seek(to: time)
            return .success
        }
    
    let skipBackwardCommand = commandCenter.skipBackwardCommand
    if(MusicPlayer.mediatype == "podcast")
    {
    skipBackwardCommand.isEnabled = true
    skipBackwardCommand.preferredIntervals = [NSNumber(value: 10)]
    skipBackwardCommand.addTarget(handler: skipBackward)
      
    }
    else{
        skipBackwardCommand.isEnabled = false
    }
    
    
   
    let skipForwardCommand = commandCenter.skipForwardCommand
    if(MusicPlayer.mediatype == "podcast")
    {
    skipForwardCommand.isEnabled = true
    skipForwardCommand.preferredIntervals = [NSNumber(value: 30)]
    }
    else{
        skipForwardCommand.isEnabled = false
    }
    skipForwardCommand.addTarget(handler: skipForward)
   
    
    
    // Add handler for Play Command
    commandCenter.playCommand.addTarget { [unowned self] event in
        if self.player?.rate == 0.0 {
            self.player?.play()
            return .success
        }
        return .commandFailed
    }

    // Add handler for Pause Command
    commandCenter.pauseCommand.addTarget { [unowned self] event in
        if self.player?.rate == 1.0 {
            self.player?.pause()
            MPNowPlayingInfoCenter.default().nowPlayingInfo?[MPNowPlayingInfoPropertyElapsedPlaybackTime] = Int(Double((self.player?.currentTime().seconds)!))
            return .success
        }
        return .commandFailed
    }

    
    
    
    func skipBackward(_ event: MPRemoteCommandEvent) -> MPRemoteCommandHandlerStatus {
                
                //self.player?.seek(to: CMTimeMakeWithSeconds(CMTimeGetSeconds((self.player?.currentTime())!).advanced(by: -30), preferredTimescale: 1))
                // print(CMTimeGetSeconds((self.player?.currentTime())!)) //Output: 42
                
                //print(event.interval)
                //self.player!.seek(to: CMTimeMakeWithSeconds(CMTimeGetSeconds((self.player?.currentTime())!).advanced(by: -30), preferredTimescale: 1))
                let currentTime = self.player?.currentTime()
                self.player?.seek(to: CMTime(seconds: currentTime!.seconds - 10, preferredTimescale: 1), completionHandler: { isCompleted in
                    if isCompleted {
                        MPNowPlayingInfoCenter.default().nowPlayingInfo?[MPNowPlayingInfoPropertyElapsedPlaybackTime] = Int(Double((self.player?.currentTime().seconds)!))
                    }
                })
                return .success
                
            }
            
            func skipForward(_ event: MPRemoteCommandEvent) -> MPRemoteCommandHandlerStatus {
                //self.player?.seek(to: CMTimeMakeWithSeconds(CMTimeGetSeconds((self.player?.currentTime())!).advanced(by: 30), preferredTimescale: 1))
                let currentTime = self.player?.currentTime()
                self.player?.seek(to: CMTime(seconds: currentTime!.seconds + 30, preferredTimescale: 1), completionHandler: { isCompleted in
                    if isCompleted {
                        MPNowPlayingInfoCenter.default().nowPlayingInfo?[MPNowPlayingInfoPropertyElapsedPlaybackTime] = Int(Double((self.player?.currentTime().seconds)!))
                    }
                })
            
                
                
                
                return .success
            }
    

}

But how can I call that from inside a View?
