Google SAML app - IDP flow through Google APP icon interupts

Can any one guide me how to fix Google SAML SSO IDP flow through APP icon.

Steps to replicate:

create saml IP in keycloak
register saml app in google workspace
link saml app in keycloak and do configurations
check sso by clicking app icon on google workspace
cookie not found/invalid request coming

There’s a post on IdP initiated login for GSuite here

And the Keycloak documentation for that is here
