We need to make sure we're converting the file to the right format (depending on engine) before sending it. We can add asis: False flag (should it be True or False by default?) - meaning if it's asis: True - we'll try to send file as is, without applying format convertion pipeline. But if it's False we'll adjust the payload if required before sending a voice/video message
