Login And Register via API with keycloak-angular

Hi guys,
Can you please help? i would like to replace the default methods:
login/register of the keycloak-angular service, but dont know how,
i would like to rout to my own login/register forms instead of the default pages
and register and login via api. is it possible? how do i overide or extend the service in angular to support my needs?

thanks,
Pini

We have documentation for that. You should probably start here: https://www.keycloak.org/docs/latest/server_development/

Thanks,
I went over the documentation, i do not see an example of chrome extension,
can you please point me to the right section?
