ios – tips on how to conform appdelegate to protocol PTChannelManagerDelegate?

I am constructing a iOS utility utilizing flutter , I am seeking to combine IOS PushToTalk framework within the utility , I’ve setup the pushtotalk iOS framework in appdelegate.swift file .On constructing the app , I get the error : Kind ‘AppDelegate’ doesn’t conform to protocol ‘PTChannelManagerDelegate’

The appdelegate.swift code is talked about beneath

    import UIKit
    
    import Flutter
    
    import PushToTalk
    
    import AVFoundation
    
    @UIApplicationMain
    @objc class AppDelegate:FlutterAppDelegate {
        
        override func utility(
            _ utility: UIApplication,
            didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
        ) -> Bool {
            
          
            GeneratedPluginRegistrant.register(with: self)
            
           
           var channelManager  = strive await PTChannelManager.channelManager(delegate: self,restorationDelegate: self)
    
            
            return tremendous.utility(utility, didFinishLaunchingWithOptions: launchOptions)
        }
        
    }
    extension AppDelegate:PTChannelManagerDelegate
    {
    
        enter code right here
         func channelManager(channelManager:PTChannelManager, channelUUID: UUID, didBeginTransmittingFrom: PTChannelTransmitRequestSource)
        {
    
        }
         func channelManager(channelManager:PTChannelManager, channelUUID: UUID, didEndTransmittingFrom: PTChannelTransmitRequestSource)
        {
    
        }
          func channelManager(channelManager: PTChannelManager, failedToBeginTransmittingInChannel: UUID, error: (any Error)?)
        {
    
        }
          func channelManager(channelManager:PTChannelManager, failedToStopTransmittingInChannel: UUID, error: (any Error)?)
        {
    
        }
           func channelManager(_ channelManager:PTChannelManager, didJoinChannel: UUID, purpose: PTChannelJoinReason)
        {
    
        }
          func channelManager(_ channelManager:PTChannelManager, didLeaveChannel: UUID, purpose: PTChannelLeaveReason)
        {
    
        }
          func channelManager(channelManager:PTChannelManager, failedToJoinChannel: UUID, error: (any Error)?)
        {
    
        }
          func channelManager(channelManager:PTChannelManager, failedToLeaveChannel: UUID, error: (any Error)?)
        {
    
        }
          func channelManager(_ channelManager:PTChannelManager, receivedEphemeralPushToken: Information)
        {
    
        }
           func incomingPushResultForChannelManager(
            channelManager: PTChannelManager,
            channelUUID: UUID,
            pushPayload: [String : Any]
        ) -> PTPushResult
        {
            return .leaveChannel
    
        }
        
        func channelDescriptor(restoredChannelUUID channelUUID: UUID) -> PTChannelDescriptor
        {}
    
    }

on constructing the app , I get the error
Kind ‘AppDelegate’ doesn’t conform to protocol ‘PTChannelManagerDelegate’
