You need tracker blocking extensions, and/or a "degoogled" version of Chrome like Thorium or Brave.

My usual loadout is Thorium + the EFF's Privacy Badger extension, and sometimes UBO.

can you say why degoogled chromium matters for tracking, or link to a writeup?

The Ungoogled Chromium project itself is a pretty good summary. In a nutshell, Chromium (whether signed in or not) "phones home" to Google for a number of reasons, and the official Chrome builds do it even more (though in harder to observe ways since the changes are closed source).
