title: How to add custom menu command to VSIX Error Context Menu
body: <p>I looked at the <a href="https://docs.microsoft.com/en-us/dotnet/api/microsoft.visualstudio.shell.vsmenus?view=visualstudiosdk-2022" rel="nofollow noreferrer">MS docs on the VS menu list</a>, and I can't find which menu ID to use.  What I want to do is write a VSIX extension that gives me a menu pick when I right click on an Error message, and it will be able to obtain the contents of the selected error message.</p>
  <p>Does anyone know if there is a way to customize that contextual menu?</p>
