Hello everyone! I'm new to IPTV and would like to ask if there's any app that would allow me to choose the channel or whatever in the smartphone and then cast it to the app installed on the android TV. All allowing me to keep using my phone as the TV is playing.

I'm currently using VLC to play the m3u playlist but it's a pain in the ass to change channels and to do anything really with the remote. So for example I could open [app I'm looking for] on my smartphone and on the Android TV and choose the channel I want to watch on the smartphone and it would play on the TV app
