GetControllerBatteryPercentRemaining() does not work

When I call the function OvrInput.GetControllerBatteryPercentRemaining(), it always returns a value of 0.

Does the GetControllerBatteryPercentRemaining() function work after OvrPlugin 1.78?

We have not been able to import the controller battery since we recently upgraded to oculus integration v50.

Also, The Test Project that integration v50 was installed also did not work.

public static extern Result ovrp_GetControllerState5(uint controllerMask, ref ControllerState5 controllerState);

function appeared to have a problem, but the OvrPlugin.DLL was encrypted and could not be verified.

Thanks for your Help!
