Most "annoyance blocker" filterlists get these. In this case it's intercom.io which I block with Adguard's Annoyances lists: https://adguard.com/kb/general/ad-filtering/adguard-filters/

I can't imagine using the internet without uBlock Origin, SponsorBlock, and a whole host (no pun intended) of filter lists.
