Can't get client meeting link, only provider link

Hello,

We need to get the meeting link for clients.

The methods listed in the API documentation only return Provider meeting links:

Method 1
RPC 2.0
POST /admin/
method: getBookingOnlineMeetingLink

Method 2
REST
GET /admin/bookings/<booking_id>/online-meeting-link

Outcome for both:
/v2/online-meeting/provider/id/(id)/hash/(hash)

The following REST call does include keys for online_meeting_id, online_meeting_hash, online_meeting_link, but values returned are always null:

INPUT
GET /admin/bookings/<booking_id>

OUTPUT
“online_meeting_id”: null
“online_meeting_hash”: null
“online_meeting_link”: null

Am I missing something?

Please could you advise how to get the meeting link for the client via API?

Thanks in advance
LC
