Another explanation for why the JWST may have seen an overrepresentation of galaxies rotating in one direction is that the Milky Way’s own rotation could have caused it.
This is a straight up citation from the article. It doesn’t mean there are other galaxies inside our own. It means the rotation of our own Galaxy may have influenced the measurements.
TLDR :
There’s no other galaxies in the Milky Way. The discovery indicates our entire universe’s rotation might have caused it!
