AndroidTV Integration Open Plex

Configuration
1

Hi Guys.

I have the Android TV integration connected to my Amazon FireTV. Is there a way that i can Open Plex application on the FireTV Cube without me using the remote? I am thinking a Toggle button that in turns Opens the app via a scene or Node Red

Thanks in advance
