Edit model context menu

I added a new option in model context menu with sl_customization function which calls a function.

 function sl_customization(cm)
     cm.addCustomMenuFcn('Simulink:PreContextMenu', @getMyMenuItems);
 end

 function schemaFcns = getMyMenuItems(callbackInfo) 
     schemaFcns = {@getLC}; 
 end

 function schema = getLC(callbackInfo)
     schema = sl_action_schema;
     schema.label = 'MyOption';
     schema.userdata = 'myUserData';  
     schema.callback = @myOption; 
 end

 function myOption(callbackInfo)
     % here I want to identify if my option was called after a right-click
     % on the model white space or if was called after right-clicked on a
     % block (I want the handle or path to this block)
 end

As I commented in the last function I want to find from where was called. I tried to find something in callbackInfo but I couldn't find what I wanted. Should I do it differently? If you need any details please let me know.

Thank you!

function myOption(callbackInfo) 
  selection = find_system(gcs, 'Type', 'block', 'Selected', 'on');
  if isempty(selection)
    disp('Nothing selected');
  else
    disp('Block(s) selected');
  end  
end
