Is there any source for a CancellationToken in Blazor WebAssembly that signals the termination of the whole application - similar to IHostApplicationLifetime.ApplicationStopping? If there is no such thing built-in what would be a good (best) practice to use instead?

I ended up creating my own with a CancelationTokenSource that is triggered when the App component is disposed of.
