You could make a comment on the file, although this will open a Talk conversation for each one.
Comments now trigger talk conversations?
That was what it did for me one day last week. I posted a message on the sidebar for a file, and in the Talk app, it opened a convo named for that file with my message.
Migrated to a new topic so we can discuss this further. Asking in the Talk public chat about this (and if it is possible to disable)… what version of Nextcloud are you on @KarlF12?
NC 25 AIO. Sorry, I was talking about the chat tab on the file, not the comments.
