I want to setup and connect WhatsApp Cloud API to Create WhatsApp Chatbot with BotSailor application that I've just bought but cannot since I got error message "Your developer account has been restricted because you violated our Platform Terms and Developer Policies. Appeal this restriction." in the link at https://developers.facebook.com/apps/?show_reminder=true

I'm a verified and Profesional Facebook user with blue tick on my profile

What should I do?
