 * By default, the copy button is only shown when the editor is hovered. To always show
 * it, change the default opacity with the following CSS:
 *
 * ```less
 * button.pce-copy {
 *   opacity: 1; // or a lower value for a semi-transparent button
 * }
 * ```
 *
 * @param label `aria-label` for the button. Defaults to `"Copy"`.
 * @param copiedLabel Temporary `aria-label` for the button after it has been clicked.
 * Defaults to `"Copied!"`.
