Allow notification sounds while Invisible

It seems to have been a few years since this was last suggested, or at least since what I've seen, but I would like to see an option in settings to set it to allow notification sounds while invisible. I don't like appearing online, for various reasons, but I do like to get notifications from messages/calls while appearing visible.

I do think this is a very niche thing to request, but like some others who've requested something similar I believe it should be possible and not too difficult to do. Granted I don't have coding experience to hold up to a massive company, but I think I could learn how to do it without breaking something else in the process.

Sorry for the long rant/description, I just thought it would be a decent idea. Isn't that what idea/feedback forums about?
