I am currently learning how to create extension for visual studio but I have an issue targeting a specific location in VS.

I've created a command and by default it add correctly the button action to the tool bar.

The place where I would want to add an option is here : (Only on NuGet package added as a reference)

I'll probably need to add specific code to target this in my command.cs, but not sure how to attack the problem.

I tried to look in Tools > Customize but even there can't seem to be able to find the reference to it.

I've tried to look online for the VS group ID so I can refer to it as a group but couldn't find it.

Thanks in advance.
