Proton Drive integration

I am very new to your platform, received some great help yesterday. They told me to run this by you. I am using Proton Drive, more and more as I have had Proton mail for many years now, and very happy to have secure email, unlike gmail, yahoo, etc. Proton Drive, like its mail service is very secure, unlike google drive. Therefore it would be nice if membership.io could integrate Proton Drive as they do drop box etc.
