Issue with REST APIs: replace user instead of adding user

hi. When I try to add a user to a group with users, instead of adding, the current users are replaced with the added one. I see the result through the web interface.

But how to add a user to the existing ones in the group () without replacing the existing ones ()?

From what I understand of the other forum post you are simply using the wrong API, to add a new object you need to use /wikis/{wikiName}/spaces/{spaceName}[/spaces/{nestedSpaceName}]*/pages/{pageName}/objects POST request which take the class and properties of the object to add as content and will automatically assign a new number to the added object.

Great, thanks a lot!
