import { useWeave } from "@inditextech/weave-react";

const MyAlignNodesToolTriggerComponent = () => {
  const instance = useWeave((state) => state.instance);

  const alignNodesTool = React.useCallback(() => {
    instance.triggerAction("alignNodesTool", {
      alignTo: ALIGN_NODES_ALIGN_TO.TOP_VERTICAL,
    });
  }, [instance]);

  return <button onClick={alignNodesTool}>Align selected nodes to top</button>;
};

Finally a final user:

Select some elements on the stage.
trigger the UI element that launches the action.

When the tool is triggered automatically the selected nodes will be aligned according to the passed params.
