Realized I don’t actually look at the “real” site, just the editor, which is very blank.

So noticed the big twitter button, that is on the default pages at the bottom, and with recent changes, decided to remove it. But how?

google gave lots of answers, but for me not the most up to date.

so here is what I did, just today:
on the main WordPress page, went to Tools >> Marketing

then on the Marketing and Integrations page:

go to [Sharing Buttons] tab.

then the [Edit Sharing Buttons] link. There you can pick from the list, found Mastodon, and “unclicked” Twitter/Facebook.

so now below, you should see Mastodon if you want to share.
