Expose existance & status of menu item in a condition or API call

I have added it in 4.458, however I have not tested it much yet.

tell application "BetterTouchTool"
	get_menu_item_details "Edit;Redo"
end tell
async function someJavaScriptFunction() {
	return await get_menu_item_details("View;Show Live View");
}

=>
{"available": true, "enabled": true, "checked": false}
