New Input System GetButton() Alternative

In the new Input System, is there a way to check if an Input Action is being performed?

I’ve found that if I do this controlScheme.Player.MyAction.activeControl it returns null if the action is not performimg.

There are other ways, but the simplest get button state of a gamepad is like this:

using UnityEngine.InputSystem;

Gamepad gamepad = Gamepad.current;
if (gamepad != null)
{
    if (gamepad.buttonSouth.isPressed)
    {
        Debug.Log("Button down");
    }
    if (gamepad.rightTrigger.ReadValue() > 0.5f)
    {
        Debug.Log("Trigger down");
    }
}
