User handles are icons that are placed around the node to run the
frequently used commands. This example shows how to render and
configure user handles and how to interact with the diagram using user handles. The userHandles property of the selectedItems can be used to add user handles to the diagram. fixedUserHandleTemplate property of the diagram provides template support for customizing fixed user handles and we provide the HTML button to delete the node.Click the templates in the property
panel, to customize the size, position, and appearance of the user handles.
