MSStickerView in SwiftUI not animating by default

I am working on a sticker app and I am building a custom sticker app in SwiftUI. I have created a custom UIViewRepresentable to allow a MSStickerView to be displayed in SwiftUI. I have local *.gif files in my project and I am loading them into the MSStickerView successfully, however when they are loaded in my iMessage sticker extension the stickers are not animating by default. When I tap on the MSStickerView the gif begins to animate, I'm not sure what else I can do to get this working properly in my app. Some sample code below:

public struct CustomStickerView: UIViewRepresentable {
    
    var sticker: CustomSticker
    
    public init(sticker: CustomSticker) {
        self.sticker = sticker
    }
    
    public func makeUIView(context: Context) -> MSStickerView {
        let v = MSStickerView()
        if sticker.fileType == .gif {
            v.startAnimating()
        }
        return v
    }
    
    public func updateUIView(_ uiView: MSStickerView, context: Context) {
        uiView.sticker = sticker.sticker
    }
}

// CustomSticker

public var sticker: MSSticker? {
        guard let imagePath = Bundle.main.path(forResource: name, ofType: ".\(fileType.rawValue)") else {
            print("Failed to get sticker - \(name).\(fileType.rawValue)")
            return nil
        }
        let path =  URL(fileURLWithPath: imagePath)
        return try? MSSticker(contentsOfFileURL: path, localizedDescription: name)
    }
