Can't see collections

On my vaultwarden, I created an organization called “family” in which I created a collection named “password shared.”
My users are members of the family organization but cannot see the collection.
When I go into admin mode, I only see my account attached to the family organization as the owner. When I try to modify the rights, they do have access and can modify the collection.
How can I add users to the Family organization? Why can’t I see the collection?
