Video reel with multiple playable videos

I want to take two videos of the same size and shape and create an uploadable reel for social media with the videos as separately playable and side by side. I think FB used to allow this on business pages, but doesn't anymore. In order to do it, I had to create this on my personal page, make it public, then share it on my business page which was not ideal at all and very time consuming. I think there must be a way to do it with Adobe Express perhaps? I haven't ever used that but wondered if anyone else had tried to do this. Must have though; it seems like an obvious thing to do.
