Android class ConnectionService

Question

Can someone just give an example of how to implement this abstract class- ConnectionService.my The idea is to use TelecomManager to make an outgoing call.

https://developer.android.com/reference/android/telecom/ConnectionService.html#SERVICE_INTERFACE

TelecomManager telecomManager = (TelecomManager)this.getSystemService(Context.TELECOM_SERVICE);
        PhoneAccountHandle accountHandle=telecomManager.getSimCallManager();
        PhoneAccount account=telecomManager.getPhoneAccount(accountHandle);
        telecomManager.registerPhoneAccount(account);

        CharSequence label=account.getLabel();
        ConnectionRequest request = null;

        Connection connection= service.onCreateOutgoingConnection(accountHandle,request);

now I need to know what will be given in the feild request and Connection service, how to implement it before that ..
