Firstly, sorry if this is not the adequate place for my question; if it's the case, let me know.
The title may seem confusing, so let me detail it: I'm more of a commenter person, and some of my comments are replied, and Lemmy notifies me of those direct replies. However, there are moments when those replies receive third-party replies, so my comment turns into some kind of "sub-thread", something that's interesting for me to read and follow. For those third-party replies, I don't receive notifications, so I have to access each direct reply that was notified so to find possible "sub-threads".
There seems to me to be no option to "receive notifications for this post/comment/reply", only the automatic opt-in of notifications for direct replies.
So really isn't there such an option? Or is this an instance-specific feature and the instance I belong to (thelemmy.club) don't have it?
Afaik what you are asking is not possible
