Hi dani.ginsberg,
Thanks for using Zoom SDK. Are you looking for the part when you are using the Zoom client and someone invites you to a meeting, a pop-up show up to accept or decline the invitation? If so, that is a Zoom IM feature, which is not included in the Client SDK. The client SDK mainly focuses on the meeting core features, and different apps have different ways of inviting others to a meeting, thus I am afraid this part needs to be handled by the developer.
Hope this helps. Thanks!
