[keycloak-user] [UMA] Submitting Permission Request

Hello, I'm trying to implement a frontend interface for requesting permissions to resource owners, however I'm having trouble understanding what a "permission_ticket" is. According to the documentation (https://www.keycloak.org/docs/latest/authorization_services/#_service_aut...), a permission request requires a "ticket=${permission_ticket}" parameter. How do I obtain this ticket? Can I build it myself? The previous section states: "The resource server sends a response back to the client with a permission ticket and a as_uri parameter with the location of a Keycloak server to where the ticket should be sent in order to obtain an RPT." But I'm not sure how I make my API/Resource Server do this. Can I request access to a resource owner through any another method? Thank you, Silva
