Blazor WebAssembly authentication demo please

[SwimlaneBuilder]

Any Blazor WebAssembly example that included these features would be great

• Detect if the app is offline, and dim/show only what's available under the current context
• Authentication to an API in the same Tenant
• Authentication to an API in a different Tenant

... and something I've had for a better workflow for all dependent apps of B2C

• Detect if the person is an administrator capable of granting the Allow Access (API permissions button) on behalf of users, to prevent the login prompt, and then invite that Administrator to click on that page with a redirect (or direct click after reading the instructions)
