### Description
Our end goal is to create a meeting with a co-host (outside the organization).  We thought that using Google Meet's v2beta, we should be able to add a "member" to the "space" with its Role being COHOST (as described in the doc at https://docs.google.com/document/d/1wOffkXVUK38-baNzRLZW85Mt11Q6YhdNS55hTigXh_w/edit?pli=1&tab=t.0) which would do what we want.

Creating a meeting, adding members, and all works.  But, when we try to add the Role, the create member endpoint returns 403.

We tried many solutions, including this one on Stackoverflow (https://stackoverflow.com/a/79133590/2321594) but nothing works.  It returns 403 even when adding the current user (the meeting organizer).

### Code
POST https://meet.googleapis.com/v2beta/spaces/q8xxxxxxxxx/members
{
  "name": "John Doe",
"email": "test@test.com",
"role": "COHOST"
}

### Output
{
  "error": {
    "status": "PERMISSION_DENIED",
    "message": "Permission denied on resource Member (or it might not exist)",
    "code": 403
  }
}

### Steps
1. Create a space.
2. Optional: add a Calendar Event with the space's conferenceId and two participants
3. Try to add one of the participants as a member with Role being COHOST.

### Notes
- We even tried putting "moderation" to "ON" in space config, but that didn't help either.
- Our end goal is to be able to add a person outside our organization as a co-host to our meetings.  So, any alternative solution would be much appreciated!
