Three things:

• the test doesn't pass
• I think there is a simpler way to do this just at the UrlParams level
• the documentation update is missing.

As I am off today I will do a quick alternative PR.

Actually, I've run out of time to do something today. What I noticed was that the URL parameters were not being parsed from the mocked router URL.

Thanks for the finding about the router URL.
The tests work locally lets see what i have setup differently!

This already checks that the widget is started in widget mode.
Hence the way it is now, it would not introduce the risk of allowing to share a unmuted link.

Following discussion: marking draft until we revisit this topic as part of expected flows for telephone/DM use cases.
