Just the "How To" for this Film Festival URL

[zivug]

Hello,
I would like to know the method to download streaming videos from mymovies.it like this: https://www.mymovies.it/ondemand/loc...i/livetheatre/
(URL active from Monday 10 August 2020 at 21:30

I repeat the method not the file.
I have tried many of the available tutorials that analyze the stream - an embedded file on Vimeo - but none work; no browser extensions: "Vimeo Video Downloader", "Simple Vimeo Downloader", "Vieo Downloader Porofessional", "Vimeo Downoader"
Not even: Video DownloaderHelper or Savefrom.net Helper succeed.
Tips?
Thank you.
