 /**
- * The `duoHandOffMessage` must be set in the client via a cookie. This is so
- * we can make use of i18n translations.
- *
- * Format the message as an object and set is as a cookie. The following gives an
- * example (be sure to replace strings with i18n translated text):
- *
- * ```
- * const duoHandOffMessage = {
- *  title: "You successfully logged in",
- *  message: "This window will automatically close in 5 seconds",
- *  buttonText: "Close",
- *  isCountdown: true
- * };
- *
- * document.cookie = `duoHandOffMessage=${encodeURIComponent(JSON.stringify(duoHandOffMessage))};SameSite=strict`;
- *
- * ```
- *
- * The `title`, `message`, and `buttonText` properties will be used to create the
- * relevant DOM elements.
- *
- * Countdown timer:
- * The `isCountdown` signifies that you want to start a countdown timer that will
- * automatically close the tab when finished. The starting point for the timer will
- * be based upon the first number that can be parsed from the `message` property
- * (so be sure to add exactly one number to the `message`).
- *
- * This implementation makes it so the client does not have to split up the `message` into
- * three translations, such as:
- *    ['This window will automatically close in', '5', 'seconds']
- * ...which would cause bad translations in languages that swap the order of words.
- *
- * If `isCountdown` is undefined/false, there will be no countdown timer and the user
- * will simply have to close the tab manually.
- *
- * If `buttonText` is undefined, there will be no close button.
- *
- * Note: browsers won't let javascript close a tab that wasn't opened by javascript,
- * so some clients may not be able to take advantage of the countdown timer/close button.
+ * Note: browsers won't let javascript close a tab (button or otherwise) that wasn't opened by javascript,
+ * so browser, desktop, and mobile are not able to take advantage of the countdown timer or close button.
