office365 graph api to assign owner rights on private groups

Question

I want to find mechanism to add specific users as owner of private groups.

I tried MS Graph API, but it looks like there is rest api to assign owner rights.

Answer 1

Add group owner allows you to add a user to the O365 group's owners.

See this sample:

POST https://graph.microsoft.com/v1.0/groups/{id}/owners/$ref
{
  "@odata.id": "https://graph.microsoft.com/v1.0/users/{id}"
}
