I have successfully created email confirmation link and sent email in ASP.NET Core using following call back link. However when I do it in Blazor, IUrlHelper doesn’t work well:

var callbackUrl = _Url.Page(
   "/Account/ConfirmEmail",
   pageHandler: null,
   values: new { area = "Identity", userId = userId, code = code, returnUrl = "~/" },
   protocol: _request.Scheme); 

I have tried using some website suggestion to register services as following but still got error.

Now I just want to switch to Blazor NavigationManager to create the callback link.

Can anyone suggest how to use NavigationManager to create the call back link? Thank you very much.
