Closed captioning integration with Rev.com

Hi! We're trying to enable live auto closed captioning with Rev.com for Zoom webinar. We're already using  Restream for livestream to our FB and YouTube pages and launch this when we begin our webinar. We cannot add Rev to the Restream platform because they don't support it. How do we keep our livestream with Restream in tact and add Rev.com closed captioning to our zoom webinar?

Thanks!
