How to prevent node selection programmatically in React Diagram?

In the Syncfusion® React Diagram, the selectionChange event is triggered when selecting diagram elements either through user interaction or programmatically. Within the selectionChange event, you can prevent the selection of a node by setting a boolean value. By default, this value is set to false. When a node is dynamically selected, this boolean value is set to true.

Based on this boolean value, the selection of the node is restricted within the selectionChange event by setting the args.cancel property to true. This prevents the node from being selected.

let isSelect = false;
selectionChange={(args) => {
 if (isSelect === true) {
   args.cancel = true;
 }
 isSelect = false;
}}
