Blazor WASM: Call Notification service from HttpInterceptor

please suggest.
I'm trying to call NotificationService from HttpInterceptor (a singleton service) and it's not working.
When I call NotificationService from component - it's ok.
NotificationService is registered and is placed in main application layout.

Is NotificationService supposed to be called not from a component ?

Looks like the same for DialogService.

Thank you.

What exactly is not working?

Notification does not appear at all. No DOM changes.

You’ve missed this most probably:
