Feature request

Which Nextcloud Version are you currently using: 30.0.10

Is your feature request related to a problem? Please describe.
when picking a file from the files app in talk, it only searches the top level

Describe the solution you'd like
I would like to search recursively

Describe alternatives you've considered
manually navigating in files and getting that file in talk somehow.....
syncing everything locally and manually navigating locally to upload in talk (not feasible if a lot more is in the cloud than locally)
