Not able to identify the submenu - UIPATH

Hi @everyone,
Am currently working with a desktop application using UiPath.
Task: Open a menu from a navigation bar. then click on the submenu in nav bar.
Am using Computer Vision for this. So first i added the screen to CV scope then i added the CV Click.
Now I need to add the screen of submenus to CV Scope. which am facing issue. I tried pressing F2 and clicked on the menu still its not adding. Please guide me @UiPathMaster @UiPath_Community @Expert
