Using the Lichess API to find all future tournaments a team is in, but no leaders have joined

[bmcdeearr]

I am a team leader and there has been an influx of requests in my Inbox to join Arena tournaments.
I wish to be proactive and find tournaments where the tournament creator has put my team into the list, but the other leaders don't know.

I checked https://lichess.org/api#tag/Teams/operation/apiTeamArena, and it was confirmed in my original thread in the Lichess Discord Support that the API only finds results where the Team Leader already joined.

Is it possible to investigate whether an API can support finding Team Tournaments where the team has been registered as a participant, but no leaders have joined yet?

USE CASE:
As a team leader on Lichess,
I would like to know which Arena Team tournaments were created
and do not have a leader assigned
So I can be proactive and add them in case others in my team want to join.

It's not straightforward. The tournament mongodb document would need an additional denormalized field to store invited team ids; that field would need to be indexed for efficient querying.
