How to use the react-mosaic-component.updateTree function in react-mosaic-component

const node = getNodeAtPath(mosaicLayout, path);
    const before = position === "left" || position === "top";
    const [first, second] = before ? [newNode, node] : [node, newNode];
    const direction = position === "left" || position === "right" ? "row" : "column";
    const updates = [
      {
        path,
        spec: {
          $set: { first, second, direction },
        },
      },
    ];
    if (config.panelConfig) {
      savePanelConfig({ id: newNode, config: config.panelConfig, defaultConfig: {} });
    }
    const newLayout = updateTree(mosaicLayout, updates);
    changePanelLayout(newLayout);
  };
