Assume this setup:

Two separate hosts on two different domains:

• one identity provider (a SSO server, which have its own front-end including login forms, profile management, etc.)
• The other one is a mere front-end which requires authorized access and is a client for the identity provider. The authentication process works perfectly.

The lifetime of the cookies issued to the identity provider host users are correctly customized using ConfigureApplicationCookie. I want to extend the lifetime of the cookies issued to the client users.

What has been tried:

• options.ExpireTimeSpan of ConfigureExternalCookie (Result: no change)
• options.Authentication.CookieLifetime of AddIdentityServer (Result: messes up everything)

Duende.IdentityServer 7.0.8
