Just a side note .....
Nova launcher, has offered, this feature, (Google Companion /Feed ) for quite a few years now.
I've been using Google feeds on my Samsung phones .... who knows... since Note 8... Note 9 days..? (no root required etc)
So i don't think to many users, will be anxious, get it on a Samsung launcher .?
(I might be wrong)
Anyway just my opinion.
Good luck. .
