    // Method Description:
    // - Attempt to convert something into another type. For the
    //   HasNestedCommandsVisibilityConverter, we're gonna check if `value` is a
    //   string, and try and convert it into a Visibility value. If the input
    //   param wasn't a string, or was the empty string, we'll return
    //   Visibility::Collapsed. Otherwise, we'll return Visible.

    // Arguments:
    // - value: the input object to attempt to convert into a Visibility.
    // Return Value:
    // - Visible if the object was a string and wasn't the empty string.
