thanks for the info, but i think that is not the issue the topic starter and i have. i do not want to invite a collaborator to our team or a project.
based on the figma documentation, you can mention collaborators, that have only a role on a file:
Team members can also mention collaborators who only have a role on that specific file or project.
and in my case i can definitely not mention collaborators on a file but only team members. so the issue still persists.
