Touchpoint

Pass ``element_id`` to click via the element's native
accessibility action (most reliable).  Pass ``x`` and ``y``
to click directly at screen coordinates instead — useful
when clicking by ID triggers an unintended action (e.g.
opens a dropdown instead of focusing a text entry).
Every element shows its position as @(x,y) in listings.
Coordinate clicks always report OK even if nothing was hit —
verify the result with a screenshot or find().

Args:
    element_id: The element ID to click.
    x: Screen X coordinate (use with y instead of element_id).
    y: Screen Y coordinate (use with x instead of element_id).
    button: "left" (default) or "right".
    double_click: If true, perform a double-click instead.
        Cannot be combined with button="right".
