docs: Removes a CDN-enabled object from public access before the TTL expires.
          Please note that there is a limit (at this time) of 25 such requests;
          if you need to purge more than that, you must contact support.
  
          If one or more email_addresses are included, an email confirming the
          purge is sent to each address.
