MPRemoteCommandCenter - Remote controls on lock screen does not show up

Here is the shorter version of my code (without API parsing):

import UIKit
import AVKit
import MediaPlayer
class ViewController: UIViewController, AVAudioPlayerDelegate {

@IBAction func buttonPressed(_ sender: UIButton){
              if isPlaying {
                   player.pause()
                   sender.setImage(playImage, for: .normal)
              } else {
                   let url = "https://myradio.com/radio.mp3"
                   do {
                        try AVAudioSession.sharedInstance().setCategory(.playback, mode: .default, options: [.mixWithOthers, .allowAirPlay])
                        try AVAudioSession.sharedInstance().setCategory(AVAudioSession.Category.playback, options: [])
                        print("Playback OK")
                        try AVAudioSession.sharedInstance().setActive(true)
                        print("Session is Active")
                   } catch {
                        print(error)
                   }
                   
                   player = AVPlayer(url: URL(string: url)!)
                   player.volume = 1.0
                   player.rate = 1.0
                   player.play()
                sender.setImage(pauseImage, for: .normal)
              }
              
              isPlaying.toggle()
         }


    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.
        overrideUserInterfaceStyle = .light
        setupRemoteTransportControls()
        requestNowPlaying()
        setupNowPlaying()
    }

// Here is the API data downloading part, so i skipped it 


    //Command Center audio controls
    
    func setupRemoteTransportControls() {
        // Get the shared MPRemoteCommandCenter
        let commandCenter = MPRemoteCommandCenter.shared()
        // Add handler for Play Command
        commandCenter.playCommand.addTarget { [unowned self] event in
            if self.player.rate == 1.0 {
                self.player.play()
                return .success
            }
            return .commandFailed
        }

        // Add handler for Pause Command
        commandCenter.pauseCommand.addTarget { [unowned self] event in

    }

    func setupNowPlaying() {
