It's on the left side of the notification barYou are certain that's an app notification? It doesn't look like any I've seen, by which I don't mean "I don't recognise that particular notification icon" but "if you hadn't said that was a notification icon I'd never have guessed". The only thing I can really say about it is that it massively violates current guidance for notification icons, so is more likely to be an old app.
The other thing to note is that since there are literally millions of apps out there it's rare that we can give definite answers for any other than fairly common apps - occasionally someone will recognise an obscure one, or manage to identify it using a reverse image search (have you tried that?), but more commonly not. Of course if it's your own phone you can just pull down the notification slide and find out, but as these usually concern a screenshot from someone else's phone the most efficient way of finding out is usually to ask the person whose phone it was.
