I need to add a custom button for EE and run a script if the user clicks on the button. basically, I know how to create a button at the core database at
/sitecore/content/Applications/WebEdit/Ribbons/WebEdit
and I know that I need call command like item:executescript(id=$Target,script={93BAF91E-1111-4C90-8A1F-5AF71C9B7033},scriptDb=master)
but I am not sure that should be set at layout option for this button at Sitecore Rock,
