Bug description

There is a bug when you're trying to move files inside of a full access link share. The modal "Choose target files" not getting directory listing for move or copy target, because the userid and path for DAV request is missing in the context of link share.

Steps to reproduce

1. Create directory d1
2. Create directory d2 inside of d1
3. Create file f1.txt inside of d1
4. Create link share of d1 with full access (Can edit)
5. Open link share in other browser (does not matter if you are being logged in to Nextcloud)
6. Select f1.txt
7. Try to move f1.txt into d2 via actions -> move or copy
8. See error: "Choose target folder" modal list is not loading

Expected behavior

The files in "Choose target folder" modal displayed correctly with only shared items to perform operations allowed with "Full access link share", and these operations are successfully made.

I see a similar problem on all the file dialogs launched by the Music app on NC28.0.0 RC4 (and also RC2). On NC 27.1.2, these dialogs worked fine. Is the legacy wrapper for the file dialogs broken again?

Sounds unrelated, this one is caused by the wrong endpoint (webdav vs dav) because of anonymous users. This did not even work with 27.1.x.
So @paulijar feel free to report a separate issue for that one with some information about it (browser console errors?).
