Detecting NSMenuItem in XCUITest

Hi, I need to test part of my app that has NSMenuItem, and I need to get the status (if its checked or not), the accessibility inspector shows the checkmark as AXMenuItemMarkChar but I cannot get the value of that too, the menuItem is associated with a NSButton which changes the NSControlStateValue but I cannot get the value of that too, either value will fix my problem. how can I get the value of either AXMenuItemMarkChar of NSMenuItem or NSControlStateValue of NSButton?
