Each leader sees their team, and nothing else

With several teams selling at once, a problem shows up that is not technical but about trust: nobody wants the leader next to them seeing their numbers.

The separation is enforced in the database, with row-level rules on profiles and bookings. A leader who edits the URL by hand does not see another team: it is not that the screen hides it, it is that the query does not return those rows.

The difference between those two things is what decides whether you can put two competing teams in the same system. Filtering on the screen holds until the first curious person.
