Log in with oauth and session

[Anag03]

Hi guys
I have the following scenario
My home page is https://home.domain.dev/auth/login, on that page I have a button to Continue
After clicking on Continue it redirects to this page https://sso.domain.dev/oauth2/xxxxxxx
On that page, I have the login form, where I can enter the email and password and click on Log in
After logging in, it redirects to https://home.domain.dev/onboarding

I'm trying this but it doesn't work, because after logging in, it redirects to the auth page again.
(I have tried many things, that's why I have that code commented)
How can I log in via UI in this scenario?
Before I used Cypress.Cookies.preserveOnce
