How to render a tooltip when hovering over the button in React Diagram?

In Syncfusion® React Diagram ,to display a tooltip on a button, we should create HTML-type nodes and define the button within a template. Bind this template to the nodes using the nodeTemplate property in the diagram. To ensure tooltips appear seamlessly, configure the Tooltip component and bind it using the mouseover event, allowing the tooltip to trigger when hovering over the buttons.

The below code snippet explains how to render a tooltip while hovering over the button

useEffect(() => {
   // Tooltips setup on nodes after mounting
   const buttons = document.querySelectorAll('.tooltiphover');
   buttons.forEach((button) => {
     const tooltip = new Tooltip({
       content: 'Tooltip from hover',
     });
     tooltip.appendTo(button);
     // Open tooltip manually using the onmouseover event
     button.mouseover = function (args) {
       tooltip.open(args.target);
     };

     // Optional: close the tooltip when the mouse leaves
     button.mouseleave = function (args) {
       tooltip.close();
     };
   });
 }, []);
