I would like to test this feature

[Marco Cocco]

Hi Is there a way to make it work in normal chrome?

I've seen the feature first party sets flag and followed the 

When I try launch crome like this:
start chrome --use-first-party-set=https://my-test:8443,https://my-other-test:8453

and set a cookie from one of the 2 domains like this:

document.cookie = "username=Billy; Samesite=Lax; SameParty; Secure";

This cookie can't be seen from the other site.

Any hint?
