Add hangfire dashboard to existing api

Hi All,
I’ve configured my .net core web api (.net core 3.1) to have both hangfire server and dashboard.
My Frontend (angular) use this api for various aspects, and the authentication is done through OAUTH 2.0 keycloak. My problem is that I cannot check my user identity after I’ve done the login in my application (http://localhost:4200) because when I click a button to redirecto to hangfire (https://localhost:5001/hangfire) nothing is passed (no bearer token) to my api…

So How could guaranteed the auth???

Best regards
