[Bug]: Federated shares can be reshared to teams, but team members can’t access them

⚠️ This issue respects the following points: ⚠️

• This is a bug, not a question or a configuration/webserver/proxy issue.

Bug description

When you receive a federated share, you can reshare it with teams - but the members of the team don't see the share.

Steps to reproduce

1. Share a file or folder with a person or group an another Nextcloud instance.
2. As the receiver of the share: Reshare the share via an internal share and see how you can select teams via autocomplete.
3. As another member of said team: See how you cannot see the share.

Expected behavior

It should be possible to share with teams (best solution!)

Or, as long as this is not implemented: Teams should not be selectable in the resharing dialog for federated shares.

Additional info

No response

No files, tests, or entry points are named. Reproduce the federated-share reshare flow with a team and trace how the share is recorded and exposed to team members; done means members can access it, or teams are excluded from the resharing dialog until support works.
