Get image or screen capture in PyWinAuto

Question

I'm currently using PyWinAuto to get the data from a FileEditor like this.

app = Application(backend='uia').connect(title='AppTitle', timeout=2)
dlg = app.top_window()
list_child = dlg.child_window(auto_id="dgFileEditor", control_type="DataGrid").children()

for item in list_child:
    for cell in item.children():
        for smaller_cell in cell.children():
            element_info = smaller_cell.window_text()
            print(element_info)

The problem I'm facing is the data I get must be verified, which has a little checkmark icon like this. But I'm unable to find the checkmark icon in the Inspect.exe, when I hover in the icon, it show in the Inspect.exe as a DataGridCell with no children or parent. Here is the image of the dataframe with the checkmark. And here is the output on Inspec.exe when I hover in the Icon.
