Azure Function exceptions are all shown as RpcException in Application Insights

I am running an Azure Function (V4) on .NET 7 in an isolated-process.
All exceptions are shown in Azure Application Insights as RpcExceptions. It looks like my function is wrapped inside this "Invoke" and that it can only return an RpcException instead of the AppUserException that I am explicitly throwing.

This results in very unclear data. What can I do?

I just made a new function to test it:

<PackageReference Include="Microsoft.ApplicationInsights.WorkerService" Version="2.21.0" />
<PackageReference Include="Microsoft.Azure.Functions.Worker" Version="1.18.0" />
<PackageReference Include="Microsoft.Azure.Functions.Worker.ApplicationInsights" Version="1.0.0" />
<PackageReference Include="Microsoft.Azure.Functions.Worker.Extensions.Http" Version="3.0.13" />
<PackageReference Include="Microsoft.Azure.Functions.Worker.Extensions.Storage" Version="6.0.0" />
<PackageReference Include="Microsoft.Azure.Functions.Worker.Extensions.Timer" Version="4.2.0" />
<PackageReference Include="Microsoft.Azure.Functions.Worker.Sdk" Version="1.13.0" />

namespace FunctionApp1
{
    public class Function1
    {
        private readonly ILogger _logger;

        public Function1(ILoggerFactory loggerFactory)
        {
            _logger = loggerFactory.CreateLogger<Function1>();
        }

        [Function("Function1")]
        public HttpResponseData Run([HttpTrigger(AuthorizationLevel.Anonymous, "get", "post")] HttpRequestData req)
        {
            _logger.LogInformation("C# HTTP trigger function processed a request.");

            throw new AppUserException("usererror");
        }
    }
}

program.cs

var host = new HostBuilder()
    .ConfigureFunctionsWorkerDefaults()
    .ConfigureAppConfiguration(builder =>
    {
        // KeyVault
        var keyVaultEndpoint = GetKeyVaultEndpoint();
        if (string.IsNullOrWhiteSpace(keyVaultEndpoint))
        {
            throw new Exception("keyVaultEndpoint wasn't provided.");
        }
        var credentials = new DefaultAzureCredential();
        builder.AddAzureKeyVault(new Uri(keyVaultEndpoint), credentials, new KeyVaultSecretManager());

        // Azure App Config
        var azureAppConfigEndpoint = GetAzureAppConfigEndpoint();
        if (string.IsNullOrWhiteSpace(azureAppConfigEndpoint))
        {
            throw new Exception("azureAppConfigEndpoint wasn't provided.");
        }
        builder.AddAzureAppConfiguration(options =>
        {
            options.Connect(azureAppConfigEndpoint)
                .UseFeatureFlags(options =>
                {
                    options.CacheExpirationInterval = TimeSpan.FromSeconds(60);
                });
        });
        builder.AddJsonFile("appsettings.json", optional: true);
    })
    .ConfigureServices(services =>
    {
        services.AddApplicationInsightsTelemetryWorkerService();
        services.ConfigureFunctionsApplicationInsights();
        services.Configure<LoggerFilterOptions>(options =>

            var toRemove = options.Rules.FirstOrDefault(rule => rule.ProviderName
                == "Microsoft.Extensions.Logging.ApplicationInsights.ApplicationInsightsLoggerProvider");

            if (toRemove is not null)
            {
                options.Rules.Remove(toRemove);
            }
        });
        services.AddSolutionServices();
    })
    .ConfigureLogging((hostingContext, logging) =>
    {
        // Make sure the configuration of the appsettings.json file is picked up.
        logging.AddConfiguration(hostingContext.Configuration.GetSection("Logging"));
    })
    .Build();
static string? GetKeyVaultEndpoint() => Environment.GetEnvironmentVariable("ASPNETCORE_HOSTINGSTARTUP__KEYVAULT__CONFIGURATIONVAULT");
static string? GetAzureAppConfigEndpoint() => Environment.GetEnvironmentVariable("AZURE_APPCONFIG_ENDPOINT");

host.Run();
