Allow copy content from view-only public link

Is your feature request related to a problem? Please describe.
When I share a Nextcloud Office-compatible file (ex. ods, odt, odp ..) in view mode via public link, I'd expect the recipient to be able to copy content from the document, being it cells (ods) or text (odt, odp). If I'm not wrong, this is not possible at the moment in the most recent version of Nextcloud and richdocuments.

Describe the solution you'd like
I'd like to allow recipients to copy text from cells and text from Nextcloud Office-compatible files when shared in view mode via public link. Preventing copying text is a plus, so that if there is the option it would be a nice-to-have, but not expected in a normal sharing scenario, I'd say.

Describe alternatives you've considered
The user can download the file, and open it with his/here local editor, but this is less flexible.

Additional context
Sharing a file with Onlyoffice in view mode via public link does allow the user to copy the content.

No files, tests, or entry points are named in the issue. Begin by locating the public-link view-mode integration for Nextcloud Office-compatible files; done means recipients can copy cells and text from shared documents, with copy prevention remaining optional.
