Allow iphone and android support webRTC

Allow new iphone and android to use jitsi without the app.

We have no plans to allow this in the short term. We are invested in the mobile apps, which can provide a much better user experience thanks to integration with system services such as CallKit.

Can you create the option to Continue without app? I think it is a bad user experience to download app, when it is not necessary

We have no plans to do that.
