Have an auto play URL for published presentations

I want to have a published presentation displayed on a public screen in the office, and auto play. I can currently manually press "play" once the page has loaded, but I would like this to be able to be done without having to press the button so there's no user intervention required.

Depending on where the report is viewed from it may or may not be appropriate to auto play, so I don't think this should be a setting on the presentation. I think it would be better to have a query parameter in the URL that can enable auto play, e.g. "?autoplay=true"

I notice that this is mentioned in a comment on this Idea
