Okta Login with keycloak


i want to integrate okta on my keycloak as a identity provider.
i am able to add identity provider as per domain
but i want to add only parent okta login screen which handles my all domain and logins like google does.
in google we add Client ID and Client Secret from google cloud service and all gmail accounts login it handles
so i want same process in okta.
is it possible to create okta idp and while click on that it leaves us to okta login screen and handles all domain through only one idp.
if is it possible please share your views and documents if available

thanking you.
