Toggle HTML using a button in tampermonkey

I have been trying to get a script working to toggle a piece of HTML when i toggle a button, But so far i have not been able to get it working,

let newImg5 = document.createElement("img");
newImg5.src = "https://www.pcinvasion.com/wp-content/uploads/2016/12/discord.jpg";
newImg5.style = `position: absolute; bottom: 15px; left: 15px; z-index: 100000; width: 50px; height: 50px; cursor: pointer;`;
document.body.prepend(newImg5);
newImg5.addEventListener("click", () => {
       toggle.html <iframe src="https://discordapp.com/widget?id=68awdawdawdawds8&theme=dark" width="350" height="500" allowtransparency="true" frameborder="0"></iframe>
});
