The words are a placeholder: this button shows only an SVG icon (one rectangle) and its code has no text, title or meaningful class/id, so the tool cannot tell its action. Click it (or find its click handler in the script) to see what it does, then write that action in 1-3 words, e.g. aria-label=\"Play video\" or aria-label=\"Close menu\"; better still, show that word on screen next to the icon.",
