Open the application after pressing accept button from the call kit

I'm facing the issue where when I accept an incoming call from the call kit screen it's not redirecting the app.

The app is still active in the background, the call is connected but the issue is app is not opening due to which the user is not able to understand that he is connected to the call.

Can you please provide me the solution that how can I launch the app when I press the accept button?
