Calendly Free plan to Whatsapp message integration

I built a Calendly free plan to Whatsapp message integration at https://watobot.xyz/free-calendly-whatsapp-integration.html . This is still unofficial & works with Calendly Free plan provided you have embedded the Calendly Calendar on a web page of yours. I earlier tried creating a Zap on Zapier to do this integration only to realize that Calendly expose webhook support only in their paid plans. So I built this integration.

I saw Calendly has an official Callender integration - https://calendly.com/integration/callendar . I was wondering if you think I can apply for submission of this plugin as well & will Calendly accept it ? 

I see two challenges

1. Calendly would ideally want more people to upgrade to their paid plan so might not want something that works on free Calendly plan. 
2. Watobot uses unofficial ways to expose Whatsapp message API, primarily for indie sellers/marketers who need automation to send out message but lead nurturing is manual. So the message gets sent out from their own number to which the prospect could respond & they respond back manually. Watobot has no support for reading messages. But this was also the reason, I did not choose to apply for the Zap to be made public as I believed it would probably fail the Zapier strict compliance policy. 
   
   If not publish as official integration, what are my other best options to make this integration reach people who actually need it ?
