When Richdocuments is enabled, OnlyOffice documents can't share its files with external shares

Describe the bug
We have Richdocuments and OnlyOffice installed in the same NextCloud. We just updated to NextCloud 31.0.6 and both apps also, Richdocuments 8.7.7 and OnlyOffice 9.12.0. Before the update we had Nextcloud 30.0.7, Richdocuments 8.5.13 and OnlyOffice 9.11.0.

After updating, if you share a file from Microsoft (docx, pptx, xslx, etc) with edit permissions with external shares by a link, you only get the download option.
If I disable Richdocuments, then it works ok.

If the user is logged, you can open the files without a problem.

I have downgraded (disabling the app) to all Richdocuments versions that work with NextCloud 31.0.6 without success to solve the problem :(

Sorry for my bad English :)

To Reproduce
Steps to reproduce the behavior:

1. Have both apps enabled and working
2. Create a .docx document and in the file sharing tab, create a External share and give to it edit options.
3. Copy the link and in a browser where you are not logged in, paste and go. Link example: https://test.test/index.php/s/b7imH5CaykkEzsq?openfile=true
4. The file opens as downladble file without option to edit (not in OnlyOffice to edit).
5. Disable Richdocuments in the apps page.
6. Reload the document in the browser where you were not logged in. The document is opened in OnlyOffice and the person can edit it, as it is expected.

Expected behavior
OnlyOffice opens the file and the person can edit it.

Reproduce the public-share flow at the documented /index.php/s/...?...openfile=true entry point with Richdocuments and OnlyOffice enabled, then compare it after disabling Richdocuments. Trace how anonymous external-share requests select the document editor; done means an external user with edit permission is opened in OnlyOffice rather than being offered only a download.
