[keycloak-user] Keycloak auto redirect to OKTA SSO page instead of clicking on button

[keycloak demo]

I have followed the guide https://ultimatesecurity.pro/post/okta-saml/ , to
configure OKTA Saml with keycloak. After this configuration, I see
Okta/saml login button on login page, clicking on which, the user is
redirected to Okta login/SSO.

Now, is there a way to avoid clicking on this button everytime such that
when the keycloak login page appears, user is auto redirected to Okta SSO
automatically instead of shown keycloak login form with okta redirect
button?
If not, is it possible to enter okta username password within the keycloak
form fields and keycloak have it validated internally from Okta?

This requirement is because the customer is using only Okta as IDP and does
not have any other like LDAP etc and clicking on a button seems overhead.
