In HTML, button cannot be a descendant of button

function findNestedButtons(element = document.body) {  const buttons = element.querySelectorAll("button");  buttons.forEach((button) => {    const nestedButtons = button.querySelectorAll("button");    if (nestedButtons.length > 0) {      console.log("Found nested button:", button);      console.log("Nested buttons:", nestedButtons);    }  });}
findNestedButtons();
