Video and audio urls

Please specify version and format if asking for help, or apply optional tags above:
Twine Version: 2
Story Format: Harlowe 3.2.1


I want to embed audio and video files but I can’t manage to find how to create compatible urls ? I tried with google drive but it doesn’t work. I don’t know how to put my audio and video files online so that I can reference them in my video and audio tags.

Thanks !
