Opening NC right menu from richdocuments is not possible if the user does not have sharing permission

Describe the bug
Usually in Collabora, the following icons are shown at the top right of the editor.

The following one allows to open the sharing tab of the nextcloud files, and from the sharing tab, you can access the details, or the comments, or the chat and video tab, which is quite useful if you want to comment or have a call at the same time you edit the document.

Howewer, this icon is not present if the user cannot share the file. But even if the user cannot share the file, he might want to comment it, or have a call.

To Reproduce
Steps to reproduce the behavior:

1. Create a folder (or a groupfolder) and an office document inside the folder
2. Share this folder with Alice, and remove the reshare permission
3. Log with Alice
4. Open the office document from the shared folder
5. Alice is not able to open the Nextcloud right menu
   

Expected behavior
Even if the sharing permission is denied, Alice should be able to open the right side menu, as for any other document with sharing permission.

Reproduce the issue by opening an office document as a user without reshare permission, then trace the richdocuments frontend entry point that decides whether the Nextcloud right menu icon is shown. Done means the user can open the right-side menu and access comments, details, chat, or video without gaining sharing permission.
