The best way to start/stop files remotely via HA on an Android TV

I have a small problem.
I have 3 x SmartTVs running Android TV.
I would now like to be able to start and stop the playback of various videos via HA Dashboard on the TV.
Example:
The first button always starts Video01 on TV 1 and the second button stops the video on TV 1 again.
I want to do the same with the other 2 x TVs.
What is the best option?
I am currently experimenting with VLC & batch files under Windows and trying to stream the videos.
But maybe you can also save the videos on a USB stick, plug it into the TV and then start/stop playback directly on the TV remotely?
