Add Registrant and Attendance Report in Meeting API

Hi there, we are trying to build the integration with RingCentral Meeting API. Everything is ok excluiding:

1. We cannot find a way to add registrants via APi. Something like zoom does - https://marketplace.zoom.us/docs/api-reference/zoom-api/meetings/meetingregistrantcreate

Is there any way to do this in your meeting API:

a) with unique Join URL for every registrant

b) with the same Join URL for everybody

a is preffer

2. Is there API to get detailed information about meeting participants. Something similar to: https://marketplace.zoom.us/docs/api-reference/zoom-api/reports/reportmeetingparticipants

If you don't support this could you pls let me know if it's in roadmap?

Thank you.
