Keycloak client baseurl is not accepting url without http

I am developing react app. And keeping keycloak for signup. After completing signup keycloak is triggering an email for email verification. When the user verify I want to redirect that verified user to this url e.g. com.abcd.xyzApp/(My app). But I am not able to set this URL(com.abcd.xyzApp/) in keycloak baseurl without http. Getting error “Error! Base URL is not a valid URL”

Is there any solution? Thanks
