Additional UI screen after login and consent on OAuth/OIDC

During Authorization Code flow, keycloak allows showing Login UI & Consent UI (with minor customization on UI and theme) before returning the authorization code, which can then be used by 3rd party app to get the access token.

Q. 1- Is there a way to redirect/show one more custom UI page after consent before auth code is returned/redirected to the 3rd party app client?

Q 2. Also, for login and consent UI itself, is there a way to redirect to another existing login/consent page hosted in a separate dockerized application exposed over https? And After login is done, somehow that application calls back keycloak indicating login was successful and consent details?

Note: This is how ORY Hydra performs OAuth. Not sure, if something similar exists in keycloak as well?
