There are two settings which govern how listed agents find and join your team. Both can be found in Team Settings, under Configuration.
Homepass determines whether someone is a listed agent by matching their verified details to listed agents found in your listings feed.
If you enable Auto-Approve Listed Agents, listed agents who request to join your team will be automatically approved.
If Auto-Approve Listed Agents is enabled, you'll also be able to Auto-Invite Listed Agents. This sends an invite via SMS to any agent in your team who hasn't yet joined your team on Homepass.
