@swiderskip I’ll jump in here in hope that it’ll save @tommy some time so he can answer to my SDK request I just mailed him 
No, you’ll NOT be able to join a “regular Zoom meeting”. As Tommy said, the fully Customizable Web SDK has nothing to do with the regular Zoom as everybody uses it these days on a daily basis. The CWS (haha, I like it) is rather a drop-in replacement for uhm… okay, maybe I shouldn’t drop alternatives here. Say, it’s something to help you create your own Zoom white label solution.
What I don’t get yet is that I read the documentation in a way, that one should be able to pull a specific media stream and take care of the rendering.
