How to check if a specific Item on a MenuItem object exist

I'm handling a MenuItem object, but this menu work with permissions filters and sometimes the option i need to interact isn't present on screen. 

To check if that option exist before send the action to the object, i access the Item in the position expected to be my option by the index and get the Caption property value. If that Caption matches with the option i expect, i send the action (click, selection, ...).

I'm looking in the SmartBear Community and Support for other ways, but not succesfully. Anyone can help?

C#:

//Items(4): Position i expect my option, if the user has permission to see it.

var expectedOptionName = "optionX";

var optionText = Menu["PopupMenu"].Items(4).Caption;

if(optionText == expectedOptionName)
{
    Menu["PopupMenu"]["Click"](4);
}
else
{
    Log["Message"]("Option is disabled for this user.");
}
