Not really. Tried myself using Edge and didn't work either. Looks more like a whitelisting of "supported" browsers (such as Safari or Firefox), more than a blacklisting of Edge.

However, it's still suspicious they aren't adding the proper support for Edge Chromium.

Also tried using the Brave user-agent. Also failed.

I suspect you didn't try out the user agent strings. Only one of those 4 is blocked.
