Where is the custom protocol mapper in Keycloak 20.0.2?

Question

I'm upgrading my Keycloak from 16 to 20.

In 16 I could use this screen to add a custom mapper.

In 20.0.2 I can't find this form in the admin panel. There is a Client scopes tab for each client, and it has an add button. But it does not allow me to define my custom mapper. I just adds predefined mappers.

Where is that form? How can I add custom mapper to a client in Keycloak 20.0.2?

IMO the old ui was a bit more intuitive in this regard. With the new one you need to:

• Go to your Realm
• Go to Clients and click on your client
• switch to 'Client Scopes'

In the 'Assigned client scope' click on your client-id-dedicated:

then you go to the following menu:

Click on 'Configure a new Mapper' and then select 'User Attribute' and you get something as follow:
