How to Set Tooltip for Fixed User Handles in Angular Diagram Nodes?

In Graphical User Interface (GUI), the tooltip is a message that is displayed when mouse hovers over an element. The Angular Diagram provides support to show a tooltip when the mouse hovers over any fixed user handle.
To set tooltip for node fixed user handles in Diagram on mouse hover, we can use the tooltip property of the fixed user handle with the tooltip content . You can also customize other properties of the tooltip, such as position, width, height, etc.

// set the tooltip for node fixed user handle
public tooltip = {
       content: 'Node fixed user handle tooltip',
       position: 'TopLeft'
}
