The example pyautogui.click('button.png') in readthedocs does not work

[douglasdcm]

Hi, how are you? I'm following the examples from readthedocs and I noticed this syntax pyautogui.click('button.png') is not working. I had the following error when running it. I had to use the locate functions like here

        Performs pressing a mouse button down and then immediately releasing it. Returns ``None``.
    
        When no arguments are passed, the primary mouse button is clicked at the mouse cursor's current location.
    
        If integers for ``x`` and ``y`` are passed, the click will happen at that XY coordinate. If ``x`` is a string, the
        string is an image filename that PyAutoGUI will attempt to locate on the screen and click the center of. If ``x``
        is a sequence of two coordinates, those coordinates will be used for the XY coordinate to click on.
    
        The ``clicks`` argument is an int of how many clicks to make, and defaults to ``1``.
    
        The ``interval`` argument is an int or float of how many seconds to wait in between each click, if ``clicks`` is
        greater than ``1``. It defaults to ``0.0`` for no pause in between clicks.
    
        The ``button`` argument is one of the constants ``LEFT``, ``MIDDLE``, ``RIGHT``, ``PRIMARY``, or ``SECONDARY``.
        It defaults to ``PRIMARY`` (which is the left mouse button, unless the operating system has been set for
        left-handed users.)
    
        If ``x`` and ``y`` are specified, and the click is not happening at the mouse cursor's current location, then
        the ``duration`` argument is an int or float of how many seconds it should take to move the mouse to the XY
        coordinates. It defaults to ``0`` for an instant move.
    
        If ``x`` and ``y`` are specified and ``duration`` is not ``0``, the ``tween`` argument is a tweening function
        that specifies the movement pattern of the mouse cursor as it moves to the XY coordinates. The default is a
        simple linear tween. See the PyTweening module documentation for more details.
    
        The ``pause`` parameter is deprecated. Call the ``pyautogui.sleep()`` function to implement a pause.
    
        Raises:
          PyAutoGUIException: If button is not one of 'left', 'middle', 'right', 1, 2, 3
