How to end GSM call programmatically on Android 10

We develop an Android app which is capable of ending a GSM call. We used this solution for years: end incoming call programmatically

On Android 10 this solution unfortunately fails. I can't find any other solution which actually works on Android 10. Any suggestions?

It is possible to stop GSM call on Android 10. Next code is in Xamarin Android API level 27 using reflection.

First request for permission:

// Check permission AnswerPhoneCalls
if (ContextCompat.CheckSelfPermission(context, Android.Manifest.Permission.AnswerPhoneCalls) != (int)Permission.Granted)
        {
            activity?.RunOnUiThread(() =>
                ActivityCompat.RequestPermissions(activity, new string[1] { Android.Manifest.Permission.AnswerPhoneCalls }, 0));
        }

Then stop GSM call by:

TelecomManager telecomManager = (TelecomManager)activity.GetSystemService(Context.TelecomService);
            var endcall = telecomManager.Class.GetDeclaredMethod("endCall");
            endcall.Accessible = true;
            endcall.Invoke(telecomManager);
