Remote control TV to show photos and videos for non tech savvy relative

Hi Everyone,

I am looking for ideas on how I can remotely present photos and videos on a TV.

My first thought was to setup a Raspberry PI and remote connect but I wonder if there is a better solution such as using a chrome cast and casting the media to the TV?

The idea is to be able to show videos and photos to my mother in law 20,000 km away.

I already have a basic home assistant setup there. My mother in law can turn the TV on and change channel but doesn’t know how to do much else technology wise.
