How to check checkbox is checked

Hello,
I am using rpa.windows to test my application(WPF) having some checkbox and not able to get checked state of checkbox.
inspect.exe is showing Toggle.ToggleState: On (1) and LegacyIAccessible.DefaultAction: “Uncheck”
are changing but not able to get these properties from RPA.Windows.List Attributes
is there any other way to handle this.
