Please provide the exception or error you saw

I'm reading the documentation here
https://angular-auth-oidc-client.com/docs/documentation/auto-login
It is written 
"You have to call checkAuth() in this CallbackComponent so that the url can be processed and set up, then redirect. Also think of calling checkAuth() in the AppComponent"
But in the code sample of Code flow PKCE auto-login
https://github.com/damienbod/angular-auth-oidc-client/tree/main/projects/sample-code-flow-auto-login-all-routes
the callback component
https://github.com/damienbod/angular-auth-oidc-client/blob/main/projects/sample-code-flow-auto-login-all-routes/src/app/callback/callback.component.ts
seems do nothing. There is a comment about business logic, but no checkAuth() at all.

Steps to reproduce the behavior

Just check the documentation of auto-login and the relative sample code

A clear and concise description of what you expected to happen.

Additional context

I try to add the checkauth() in my callback implementation but it generate a loop and then an error, so I try to remove it and now I have problem with the refresh token: it said there is no refresh token, but a refresh (F5) seems to fix all. Can you fix or explain the discrepancy?
