I guess this is supposed to be an install step but I am never asked if I want to do the import. I ligbintobmy MS account and the install complètes great, but that's the end. I'm using a pixel2 XL on Android 9.
The Pixel 2 launcher doesn't import from other launchers as far as I recall. (I've reinstalled the firmware dozens of times, but I can't remember being asked if I wanted to import the launcher settings from another launcher.) And it doesn't do backup/restore either.
