azure active directory - Blazor Standalone PWA offline Authentication/Authorization with AAD

Question

I had a look a lot of days to find a solution for my problem regarding offline authentication of a user in my Blazor Standalone PWA.

With .Net 5.0 I changed the Authentication scenario on Azure AD from Web to SPA. After that change, my PWA was not able to login the user in offline mode. I work on Program.cs with AddMsalAuthentication and save the tokens and ID's in local storage with help of MSAL.

If I'm online everything works like expected and I can login with the users and the tokens will be stored in local storage. After changing the online state, the PWA try to get the openid-configuration data from azure. I tried to also serve this request with the service worker, which worked quite fine but the token request after that fails also.

I searched and found the CarChecker app and the docs as well but this didn't solve my problem. Did I missed something or is there really no way, to make offline auth workable on Blazor Standalone PWA's?
