Hi Raj,
Thanks for the reply. If you are referring to the invite other features in our Zoom client, that is an IM feature, which is not included in the Client SDK, as the client SDK is mainly for the meeting features. You may leverage the interfaces in https://zoom.github.io/zoom-sdk-ios/interface_mobile_r_t_c_invite_helper.html to get the invite related information, and send the info to another person to use those info to join the meeting.
Hope this helps. Thanks!
