About using an external SDK for Native App in Bubble.

Those are all tough questions. I can tell you that if you are asking those questions for yourself you are heading in the right direction. I’m just not going to be much help in giving you specific direction. Other than yes if you can put together a plugin that implements Agora with OS Native controls then you should be able to put it into marketplace. Now whether or not that gets you a return on your invested development time…that’s a whole other story.
