Please provide a simple "guest only" client

[thenktor]

Hello,

please provide a simple "guest only" client for business users that can be run without installation (just download and run).
A lot of businuess users still have to use Edge or even Internet Explorer and don't have permissions to install third party browsers (Firefox, Chrome). Therefore they cannot join a Wire conversation because the Microsoft browsers are not supported for video calls and desktop sharing.
A wire client that can be run without installation could mitigate this problem.

Thanks
