No way to set UserId / UserEmail in AspNetCoreHttpContext when using AirbrakeMiddleware

[ja6lee]

• Sharpbrake version: Client: 5.1, Http.Middleware 3.1
• .NET platform version: 3.1.301
• Framework name & its version: AspNetCore.App 3.1.5

Airbrake config

var config = new AirbrakeConfig
{
    ProjectId = Environment.GetEnvironmentVariable("AIRBRAKE_PROJECT_ID"),
    ProjectKey = Environment.GetEnvironmentVariable("AIRBRAKE_PROJECT_KEY"),
    Environment = Environment.GetEnvironmentVariable("ASPNETCORE_ENVIRONMENT"),
    Blocklist = new List<string> { "password" },
    IgnoreEnvironments = new List<string> { "Development", "Local" }
};

Description

We are looking to set UserId and UserEmail in AspNetCoreHttpContext or be able to override AspNetCoreHttpContext when using AirbrakeMiddleware.

We are using https://github.com/airbrake/sharpbrake#aspnet-core-middleware in our Startup we have:

var notifier = new AirbrakeNotifier(config);
notifier.AddFilter(notice =>
{
    // some ignoring of specific exceptions
});     

app.UseAirbrake(notifier);

When checking the notice in the filter block, notice.HttpContext is a AspNetCoreHttpContext which is expected, since it is created here:

sharpbrake/src/Sharpbrake.Http.Middleware/AirbrakeMiddleware.cs

Line 70 in 5d13403

notifier.SetHttpContext(notice, new AspNetCoreHttpContext(context));

However AspNetCoreHttpContext doesn't set the UserId or UserEmail and doesn't give access to the underlying HttpContext where we would be able to access them (eg. something like context.User.FindFirst("userId")).

Would it be possible to expose the underlying HttpContext or the User associated with it in AspNetCoreHttpContext or provide a way to set these / customize these? Or am I missing a way to do this that already exists? (I tried searching the repo / googling, but didn't find much).

Thanks!
