Deploy gRPC app on App Service with Rest api endpoint

I have been following [How-to deploy a .NET 6 gRPC app on App Service](https://github.com/Azure/app-service-linux-docs/blob/master/HowTo/gRPC/use_gRPC_with_dotnet.md)

When I add this to my project it breaks everything else in the project, swagger wont even load anymore let alone all of the other rest api endpoints, everything is returning connection refused.

```
builder.WebHost.ConfigureKestrel(options =>
{
options.ListenAnyIP(8080);
options.ListenAnyIP(8585, listenOptions =>
{
listenOptions.Protocols = Microsoft.AspNetCore.Server.Kestrel.Core.HttpProtocols.Http2;
});
});
```

Is it possible to mix gRPC and rest api end points in the same project?
