Create an OAuth App - where to start / different features

Hello everybody,

I’m new to the whole Zoom API and I want to create an app that has access to the chat within the meeting the admin started as well as to all the participants’ reactions,
Is the OAth App the right way and know that sounds pretty dumb, but I don’t know how and where to start.

I created an OAth App and got the access token (tested it on Postman and also managed to create a meeting), but I have no idea how to set up the app right and how I get access to the chat in a running meeting or the reactions from the participants at the moment a new message or reactions appears.

I guess I do not really understand the whole concept and how such a created app works exactly, how to activate the app and how this app can have access, etc… >.<

I would be very happy about any help - thank you very much.

Whats your preferred choice for writing the code? the docs have plenty of examples for javascript and for native apps.

Don’t they help?
