How do I create this?

I want to create something like this. A side menu that changes the content in the same container. It doesn’t need to be a video.

Sorry, I’m a total idiot who has no idea what he’s doing. I’d appreciate the help.

Kinda simple, here’s a video in which I’ve shown how this is done.

You just need to use Click Interactions instead of Hover if you want the item to change on click.
