I'd wait for spectroscopic confirmation before declaring this the most distant discovered galaxy.
Last I read about this (6 days ago), this was just a galaxy candidate, based on photometric measurements (not a spectrum).[0] It still could be some different type of object. The spectrum will give much more information.
It's exciting of this discovery pans out, and it's exactly the sort of thing JWST is supposed to find, but it's still too early to say that this object has been definitely determined to be a distant galaxy.
