How to use toBase64Image()? documentation is limited.

[Udemology]

I am trying to understand toBase64Image but the description is very concise in the API section https://www.chartjs.org/docs/latest/developers/api.html.

Is there somewhere else that covers more information?
I understand how to use toDataURL() which I guess is quite similar to toBase64Image().

My goal is to create a download button that would extract the canvas as an image. I am able to to this with toDataURL(). But is there a way to do this with toBase64Image().

Please let me know if there is more information about this item.

Very similar:

Chart.js/src/core/core.controller.js

Lines 935 to 938 in ec67123

	toBase64Image(...args) {
	return this.canvas.toDataURL(...args);
	}
