How to obtain a Requesting Party Token (RPT) by API

Hello,

I searched for RPT Keycloak / RedHat documentation.

But both URL does not explain “How to get it”, it only when you decode an RPT, how to introspect an RPT. Can you provides how to get it?

This example other product explain it.
From “Create a Permission Ticket” to " Obtain a Requesting Party Token" with crystal clear explaining.
