Hi @Ana_Patricia_Garcia - is F8 is the shortcut key to open that window. If so, instead of using click you can use normal activity Send hotkey to send the keyboard keys on to the screen/Ui element
@Ana_Patricia_Garcia - It looks like you are using Modern Design that is why you were not able to find the right one. Please follow below steps to switch to classic design (Just for safe side take a back up of our code)
→ Right click on your project
→ Choose Project Settings
→ Make sure you disable the Modern Design Experience
