[BUG] Access WebDAV files from "https://www.office.com/?auth=1" failed

When trying to access WebDAV files to open in Office 365 using Edge browser on Windows 11 it fails with error message:

{"error":"Strict Cookie has not been found in request"}

I am signed in with my Hotmail account in Office Apps in windows and signed in to the same account on Office.com.

This error shows up by clicking items listed in "Recently opened" under Quick Access on homepage of Office.com as below screenshot:

The file I'm trying to open:
https://EXAMPLE.REDACTED.com/remote.php/dav/files/REDATCED/Documents/Finance/Master%20Account%20Information.xlsx?login_hint=REDACTED%40hotmail.com&ct=REDACTED&wdOrigin=OFFICECOM-WEB.MAIN.EDGEWORTH&wdPreviousSessionSrc=HarmonyWeb&wdPreviousSession=REDACTED

This occurs to all links pointing to nextcloud webdav in recently opened list.

I am able to open Excel natively in Windows via app, and navigate to mounted WebDAV folder and it opens OK.
Just not within the web browser with Office 365.

I am also able to open other onedrive publicly shared excel files in Office 365 (e.g. VIC_Energy_Tables).

I am not sure where this bug/issue should be raised, as I couldn't find the generic "files" issues page.

Nextcloud AIO Version: 7.5.1
Nextcloud Version: 27.1.3.2
PHP Version: 8.1.24
Windows 11
MS Edge 118.0.2088.69

The report names no source file or test. Start by reproducing the Office.com Recently opened flow with the supplied WebDAV URL and inspect the request that returns “Strict Cookie has not been found in request”; done means determining whether the failure is in Nextcloud’s WebDAV handling or the external Office.com integration and documenting a verified resolution path.
