Select Canvas Node using go.Diagram

Question

I am able to click on the required canvas node, but also needed to select the node prior to clicking '+' button attached to it

//get a reference to the diagram object
const diagram = go.Diagram.fromDiv(document.getElementsByClassName("diagram-component")[0])
    
//using the diagram object find a node by name
const node = diagram.findNodesByExample({text: "capeutil"}).first()
    
//once you have the node you can expand it with the following command
node.findObject('ButtonButton').click(null, {part:node});

Need to help to select node by text

Answer 1

If you have a reference to a node, you can select it by calling Diagram.select

diagram.select(node);

Note that this clears any other selection the Diagram may have.
