Programmatically open popup in Safari Web Extension

I have a Safari web extension that needs the ability to open the popup when the user interacts with a modal coming from the content script.

There is a native message handler that comes with the safari web extension when you first create it:

import SafariServices
import os.log

class SafariWebExtensionHandler: NSObject, NSExtensionRequestHandling {

    func beginRequest(with context: NSExtensionContext) {
        let item = context.inputItems[0] as! NSExtensionItem
        let message = item.userInfo?[SFExtensionMessageKey]
        os_log(.default, "Received message from browser.runtime.sendNativeMessage: %@", message as! CVarArg)

        let response = NSExtensionItem()
        response.userInfo = [ SFExtensionMessageKey: [ "Response to": message ] ]
        print("hit")
        
        context.completeRequest(returningItems: [response], completionHandler: nil)
    }

}

I have the permissions to send a native message, I've seen some examples online where you can access the SFSafariApplication module from SafariServices and open the popover. But I can't seem to access SFSafariApplication in this module.
