[VB]Accessing Toolbar Buttons Added Using A VSIX Extension

I am working on a VSIX Extension for Visual Studio 2017 (this will be my first extension). I have created an AsyncPackage and added several Custom Commands. I have modified the *.vsct file, and the Custom Commands successfully show up in the Visual Studio 2017 toolbar, and clicking them successfully calls their Execute methods. My next step is to figure out how to access the commands/buttons to be able to enable/disable them. What do I need to do to access the buttons from codebehind (and like I said, this is my first extension)? Thanks.
