OnTokenValidated event not triggered - asp.net-core

Question

What I'm trying to do is add a claim after authentication. The following example of triggering an OnTokenValidation event not actually working.
I'm using Microsoft.Identity.Web to authenticate on Azure AD. That part works! How can I register events using AddMicrosoftIdentityWebAppAuthentication to add custom claims
services.AddMicrosoftIdentityWebApiAuthentication(_configuration);
services.Configure<MicrosoftIdentityOptions>(OpenIdConnectDefaults.AuthenticationScheme, options =>
{
options.Events = new OpenIdConnectEvents
{
OnTokenValidated = ctx =>
{
var claims = new List<Claim> {
new Claim(ClaimTypes.OtherPhone, "somevalue")
};
ctx.Principal.AddIdentity(new ClaimsIdentity(claims));
return Task.CompletedTask;
},
};
});

You are using AddMicrosoftIdentityWebApiAuthentication, so the events that will be triggered are JwtBearerEvents.
You can set them up as below (.NET 6 API):
// Add services to the container.
builder.Services
.AddAuthentication(JwtBearerDefaults.AuthenticationScheme)
.AddMicrosoftIdentityWebApi(builder.Configuration);
// Enable PII for logging
IdentityModelEventSource.ShowPII = true;
// Configure middleware events
builder.Services.Configure<JwtBearerOptions>(JwtBearerDefaults.AuthenticationScheme, options =>
{
options.Events = new JwtBearerEvents
{
OnTokenValidated = ctx =>
{
var accessToken = ctx.SecurityToken;
Debug.WriteLine("[OnTokenVaidated]: I can do stuff here! ");
return Task.CompletedTask;
},
OnMessageReceived = ctx =>
{
Debug.WriteLine("[OnMessageReceived]: I can do stuff here! ");
return Task.CompletedTask;
},
OnAuthenticationFailed = ctx =>
{
Debug.WriteLine("[OnAuthenticationFailed]: Authentication failed with the following error: ");
Debug.WriteLine(ctx.Exception);
return Task.CompletedTask;
},
OnChallenge = ctx =>
{
Debug.WriteLine("[OnChallenge]: I can do stuff here! ");
return Task.CompletedTask;
}
};
});
