Need guidance to create "in game" tv screen with ability to change channels and start and pause

I’m relatively new to UE4 and am not a C++ coder. I’m learning Blueprints though. I have an ArchVis model that has a TV. I want to be able to walk up in VR and change channels and also ‘start’ and ‘pause’ manually.

All the tutorials I find online for Media Player are proximity triggers and none discuss changing the content manually “during gameplay”. I’ve found ‘Playlist’ and that works in the editor but I can’t find any tutorial or guidance so that I can create an HUD to allow me to change to any of the videos in my playlist while in the game. I can’t find any tutorials on creating video playback controls (play, pause, etc. ) on an HUD while “in game.”

Anyone have any suggestions for tutorials or assistance?
