How to Remove Tooltip From Nodes and Connectors in JavaScript Diagram?

In our Graphical User Interface (GUI), a tooltip appears when you hover your mouse over an element. This message provides additional information to enhance your experience and understanding of the interface.
If you prefer not to see these tooltips, you can easily remove them by disable the tooltip constraints for nodes or connector respectively in JavaScript Diagram.
Below is a code example demonstrating how to disable the tooltip for nodes/connectors:

ej.diagrams.Diagram.Inject(ej.diagrams.HierarchicalTree);
//Initializes nodes for diagram

var nodes = [
 {
   id: 'Steve-Ceo',
 },
 {
   id: 'Kevin-Manager',
 },
 {
   id: 'Peter-Manager',
 },
 {
   id: 'John-Manager',
 },
 {
   id: 'Mary-CSE',
 },
 {
   id: 'Jim-CSE',
 },
 {
   id: 'Martin-CSE',
 },
];
//Initializes connectors for diagram
var connectors = [
 {
   id: 'Steve-Ceo_Kevin-Manager',
   sourceID: 'Steve-Ceo',
   targetID: 'Kevin-Manager',
 },
 {
   id: 'Steve-Ceo_Peter-Manager',
   sourceID: 'Steve-Ceo',
   targetID: 'Peter-Manager',
 },
 {
   id: 'Peter-Manager_John-Manager',
   sourceID: 'Peter-Manager',
   targetID: 'John-Manager',
 },
 {
   id: 'Peter-Manager_Mary-CSE',
   sourceID: 'Peter-Manager',
   targetID: 'Mary-CSE',
 },
 {
   id: 'Kevin-Manager_Jim-CSE',
   sourceID: 'Kevin-Manager',
   targetID: 'Jim-CSE',
 },
 {
   id: 'Kevin-Manager_Martin-CSE',
   sourceID: 'Kevin-Manager',
   targetID: 'Martin-CSE',
 },
];

var diagram = new ej.diagrams.Diagram({
 width: '100%',
 height: '650px',
 //Uses layout to auto-arrange nodes on the diagram page
 layout: {
   //Sets layout type
   type: 'HierarchicalTree',
 },
 nodes: nodes,
 connectors: connectors,
 //Sets the default properties for nodes
 getNodeDefaults: (obj) => {
   obj.shape = {
     type: 'Text',
     content: obj.id,
   };
   obj.width = 100;
   obj.height = 40;
   obj.backgroundColor = '#6BA5D7';
   obj.shape.margin = {
     left: 5,
     right: 5,
     top: 5,
     bottom: 5,
   };
   //define tooltip
   obj.tooltip = {
     content : obj.id
   }
   //disable the tooltip for node
   obj.constraints = ej.diagrams.NodeConstraints.Default & ~ej.diagrams.NodeConstraints.Tooltip
   return obj;
 }, //Sets the default properties for and connectors
 getConnectorDefaults: (connector, diagram) => {
   connector.tooltip = {
     content : connector.id
   }
   connector.type = 'Orthogonal';
   connector.constraints = ej.diagrams.ConnectorConstraints.Default & ~ej.diagrams.ConnectorConstraints.Tooltip
   return connector;
 },
});
diagram.appendTo('#element');
