Possibility of autoplaying videos in gallery

Site URL: https://www.nickdavid.co.uk/film-new

Hi, My goal is to try and find a way for the videos in this gallery block on this page to autoplay.

My question is if there is a way at all for them to autoplay in gallery mode or do they need to be embedded directly into the page? They are in a grid gallery to make it easy for the client to upload themselves.

I want to try and make one of the scenarios below to work:
Scenario 1: One or two videos autoplay when opening the page that I choose by selecting autoplay in the embed settings (when embedding to gallery).

Scenario 2: Randomly chooses a video to autoplay in the grid. all videos are embedded in gallery with the option of autoplay turned on. The site decides to autoplay a random video for a few seconds and switches over to another one that autoplays.

Thank you for your support. Let me know if I can clarify any more.

Were you ever able to figure this out?

Also looking for a solve to this!
