Can I Track When My Custom Canvas Is Ready?

You absolutely can. We’ve introduced a new event, customCanvasReady, that you can listen for like this:

const handleCustomCanvasReady = () => {
  // do whatever you like here
}
element.addEventListener('customCanvasReady', handleCustomCanvasReady);

More information on handling events can be found in our “Interacting With Your Embeddables” documentation.
