[keycloak-user] Assign role to user using keycloak settings

Hi All, I have enabled the email verfication flow for user registration. However, I am wondering whether there is any way to assign a role to the user once Email has been verified. I understand that this could be achieved by calling REST APIs but can we do this through some keycloak configuration? Also, is there any way to assign a role after user successfully links his profile with one of the IdP (e.g. Google, Facebook)? Thanks and Regards, ​KK
