postMessage and addEventListener once

Lines 43 to 45 in c76399c

	window.addEventListener('message', receiveMessage, {
	once: true,
	});

Because I am running Vue dev-tools, and it is sending messages for hot reload, I was confused. Sometimes I receive the token and most of the time I was not.

After debugging I've found adding once was not a good idea, instead I removeEventListener after receiving the token.
