removeEventListener not working.

I don't seem to understand why I can't remove the event listener where I added a text through insertAdjacentText when clicked. I really hope someone helps me. I've gone through hours trying to debug it.

const header = document.querySelector(`header h1`);
const button = document.querySelector(`header button`);

function addText() {
   header.insertAdjacentText(`afterend`, `Yeah`);
   console.log(`yeah`);
}

header.addEventListener(`click`, addText);
button.removeEventListener(`click`, addText);

You've added listener to the header but you remove it from button.
Why it should work?

The element, event and callback together work like a signature.

You must remove the handler from the same element that you put it on or else the signature will be different.

I guess this is a common Javascript Problem.

But please correct me when I'm wrong.
