Possible to redirect browser authentication flow after identity provider error?

Hello,
I use keycloak 20, my browser authentication flow has Identity Provider Redirector step to integrate external idp provider by saml. If I click ‘cancel’ in external IDP authentication, it sends to keycloak saml response with following error:

<saml2p:Status>
<saml2p:StatusCode Value="urn:oasis:names:tc:SAML:2.0:status:Requester">
<saml2p:StatusCode Value="urn:oasis:names:tc:SAML:2.0:status:AuthnFailed"/></saml2p:StatusCode>
<saml2p:StatusMessage>An error occurred.</saml2p:StatusMessage>
</saml2p:Status>
</saml2p:Response>

Keycloak shows ‘We are sorry…’ page with ‘An error occurred’ text.
Is it possible to make flow to redirect browser to external error page instead of keycloak ‘We are sorry’ page when external IDP sends such saml error?
regards, Matti
