Debug ASP.NET Core with Multiple Browsers from VS Code on MacOS

I recently needed to launch different browsers for debugging a .NET Core app in Visual Studio Code on a MacOS.

A quick Google search yielded how to launch different browsers from VS Code for debugging ASP.NET Core, but this was Windows centric. While the changes below are simple, I thought I would document them anyway.

Here is the whole launch.json file for reference. The important bits are in the osx sections.

   // Use IntelliSense to find out which attributes exist for C# debugging
   // Use hover for the description of the existing attributes

Thanks to Anaruj for the original post! This was a quick post as a breadcrumb for me - I know I will need this again! Maybe it will help someone else as well.
