Feature request: Function to stop (embedded) bird

I am working on adding Pocket Bird to my website. My usual pattern for features like this is to allow the user to enable and disable them with a checkbox. Right now, it works like this:

const showBirb = () => {
	document.getElementById("birb-shadow-host").classList.remove("hidden");
}
const hideBirb = () => {
	document.getElementById("birb-shadow-host").classList.add("hidden");
}

It would be nice, however, to be able to call a function when using the CDN that gracefully terminates the script, and another to start it again so that users who don't want the bird (lord knows why) don't have to have it running in the background anyway.
