making #cx as default SMS app Android

[Jzm91]

hello, I have an app on my Android device that automatically sends some SMS, I am trying to work out a way to have the SMS go through 3cx automatically (maybe through Twilio as the mobile number is with Twilio) I have thought about trying to get another messaging app that could be integrated but so far all I have come up with is brick walls! any advice would be very appreciated!
