Blazor Server Teams App — How to use Teams authentication with AuthorizeRouteView?

I'm building a Blazor Server app integrated with Microsoft Teams, and I want to use AuthorizeRouteView to protect certain pages/routes based on Teams authentication.

I found official Microsoft samples, but for some reason there is not a single blazor project, although if create a project in VS, we get a blazor server app

In the Vs blazor template, there's logic to sign in and fetch the user profile like this:

private async Task ShowProfile(){    IsLoading = true;    var tokenCredential = await GetOnBehalfOfCredential();    var graph = GetGraphServiceClient(tokenCredential);    Profile = await graph.Me.GetAsync();    UserPhotoUri = await GetPhotoAsync(graph);    IsLoading = false;    ErrorMessage = string.Empty;}private async Task ConsentAndShow(){    try    {        await teamsUserCredential.LoginAsync(_scope); // popup login        NeedConsent = false;        await ShowProfile();    }    catch (ExceptionWithCode e)    {        ErrorMessage = e.Message;    }}

From what I understand, teamsUserCredential.LoginAsync(_scope) triggers a popup (auth-start.html & auth-end.html) and returns an access token for the given scopes.

I want to completely block access to the app unless the user is accessing it from inside Microsoft Teams.

Question:How can I wire up this Teams authentication flow to work with Blazor's built-in AuthorizeRouteView?

Any working examples would be appreciated!
