While using pywinauto for automated testing, I encountered a situation where I needed to retrieve the title (name) of a child control for evaluation. I can see the element's information in inspect.exe, but it's not present in pywinauto's control tree. I noticed that the element's attributes are IsControlElement=false and IsContentElement=false. How can I retrieve the text value of this child control?The information for these two elements is as follows:
