 * Typical Amazon cleverness, let down by their inability to communicate. Turning
   on plugin causes fatal errors, no clue as to how to fix or any documentation 
   on exact php modules or setup required. I tried for a couple of hours and gave
   up.
    `PHP Fatal error: Uncaught Error: Call to undefined method GuzzleHttp\Promise\
   Coroutine::of() in /var/www/html/wp-content/plugins/amazon-polly/vendor/guzzlehttp/
   promises/src/functions.php:362`
