Open a podcast via URL in a browser and enforce autoplay

Is there a way to open a podcast (via its URL) in a browser (say: Firefox) and, e.g. by adding something to the URL, force it to play right away when the podcast gets called?

For example use this URL

https://tasteofharmony.podigee.io/11-colombia-spain-ireland

(which is indeed one of the actual podcast episodes I want to play that way).

I imagine something like adding

&autoplay=1

to the URL, and thus make the podcast play right way. However, this trick (which I took from Youtube) does not work as simply as I hoped.

Any ideas or suggestions?
