Webex API - Query participant and Expelling participant intended use

[MaksymRossiitsev]

Hello,
I'm working on the Webex API integration now, got a few questions:
- Meeting invitations: Once meeting is created, is it possible to call invitee into the meeting?
There's "/v1/meetingParticipants/query" endpoint, but I can't see what it does exactly, while trying this out on the API documentation page (https://developer.webex.com/docs/api/v1/meeting-participants/query-meeting-participants-with-email)
Is it supposed to only send out email invitation, or should this produce any kind of UI notification on the client, and it is only limited by the demonstration, so I can't see any effect?

- Expelling a participant: I can see there's an option to expel a participant from the meeting (https://developer.webex.com/docs/api/v1/meeting-participants/update-a-participant)
But whenever I try this out on the doc page, it doesn't seem to do anything to the meeting participant. I can see that the UI triggered expel action does remove participant from
the call, but whenever I try that out using the demo page, it doesn't seem to do anything (except that the participants are not populated within the list of participants anymore).
Is it supposed to work similarly to the UI triggered expel action, but is limited by the demo capabilities, or is it meant for a different purpose?

Thank you!

Meeting invitations - Calling the invitee is not possible.

Query Meeting Participants with Email - Query participants in a live meeting, or after the meeting, using the participant's email. 
This is only used to know whether or not a participant is a host/  co-host/ video enabled/ present state/ etc..

Update a Participant

As per the API doc, The ‘mute/unmute’, 'admit' and 'expel' a meeting participant requests will return a successful response and update the state in the API, but the changes will not be applied to the Webex Meetings App participants. The inconsistent behavior in Webex Meetings App will be corrected in a future release.
Workaround: Turn on closed captions OR the Webex Assistant.
Also, please note it can only be done by the host of the meeting. It requires the meeting:participants_write scope.
