Invite links, join requests and approving new members
What it is
Every group has a primary invite link. Admins can add more, each with a name only admins see, a time limit, a member cap or admin approval, and track who joined through each. With approval on, people send a request; admins see each applicant's public photo and bio, then decide.
How to do it

- Bots screening requests (since June 2026 even with a Mini App quiz) need the Invite Users via Link right.
With Gem
Gem makes a join-request link for each connected group, the «door», and approves requests by your project's rules and each person's language; a request to the wrong language's group is declined and the person gets the right one. Everyone also gets a personal invite link, `gem.bot/<name>?i=<code>`; the first invite counts.
