I own a Sony KD55XH90 with Android TV and I use the Molotov app to watch TV. The thing is, the app is not usable with the numeric buttons of my remote. When I press "1" for exemple it switches to the integrated TV player, which in my case isn't plugged on anything.

Is there a way to change this default TV Player to something like molotov, map the numeric button of my remote to an app, or anything like that?

I don't want to plug anything to my TV since it can do everything I want and I don't want to duplicate features.
