To be clear.
the category is already set to only allow our employees/admins and the private group that was already created.
The invite give them a link which takes them where they can accept. when accepted puts them in the group and is set to send them to the “about this category” topic in the category where we are posting some instructions for them.
I am asking if there is a way to prevent any random person who may get their hands on the link from gaining access
