Customize automatic Track Page View events

[Shaker96]

Hello,

I am trying to customize the automatic track page view events. Need to modify the name param from "not_specified" to something else and also add some custom data to the properties param of the IPageViewTelemetry

In an attempt at this I created a custom telemetryInitializer class

using Microsoft.ApplicationInsights.DataContracts;
using Microsoft.ApplicationInsights.Extensibility;

public class CustomTelemetryInitializer : ITelemetryInitializer
{
    private readonly IServiceProvider _serviceProvider;

    public CustomTelemetryInitializer(IServiceProvider serviceProvider)
    {
        _serviceProvider = serviceProvider;
    }

    public void Initialize(ITelemetry telemetry)
    {
        if (telemetry is PageViewTelemetry pageViewTelemetry)
        {
            if (string.IsNullOrEmpty(pageViewTelemetry.Name) || pageViewTelemetry.Name == "not_specified")
            {
                pageViewTelemetry.Name = "QA Name";
            }

            pageViewTelemetry.Properties["CompanyName"] = "Pancakes";
        }
    }
}

// in program.cs
builder.Services.AddBlazorApplicationInsights(config =>
{
    config.ConnectionString = builder.Configuration["ApplicationInsights:ConnectionString"];
    config.AutoTrackPageVisitTime = true;

}, async applicationInsights =>
{
    var telemetryItem = new TelemetryItem()
    {
        Tags = new Dictionary<string, object?>()
        {
            { "ai.cloud.role", "SPA" },
            { "ai.cloud.roleInstance", "Blazor Server" },
        }
    };

    await applicationInsights.AddTelemetryInitializer(telemetryItem);
});

builder.Services.AddSingleton<ITelemetryInitializer, CustomTelemetryInitializer>();

This does intercept some telemetry from the app, but not the ones triggered by this library, I realize that BlazorApplicationInsights' implementation of AddTelemetryInitializer receives a TelemetryItem instead of a ITelemetryInitializer.

Thank you in advance for any assistance!
