Hey folks,

Is there some rate limit on [sendAppInvitation](https://appssdk.zoom.us/classes/ZoomSdk.ZoomSdk.html#sendAppInvitation) call?

The use case is as follows:

- host joins a meeting and invites all participants to the app via `sendAppInvitationToAllParticipants`
- most of the meeting participants join afterwards, so we invite them by listening to `onParticipantChange` and calling `sendAppInvitation` when new participant joins the meeting

Should we expect some rate limiting to occur?

Thanks!
