I Don't Add My WhatsApp No With Pabbly Chatflow

Hello Pabbly Support,

I am trying to connect my existing WhatsApp Business App number +91 8617288700 to Pabbly Chatflow while continuing to use the same number in the WhatsApp Business App.

My Facebook account has Full Control access to my Facebook Page, Chatterjee Service Centre. However, during Meta Embedded Signup, I see: “You don't have any existing phone numbers. Create a new one.”

I do not want to create a new or virtual number. Please confirm whether WhatsApp Business App Coexistence is supported and enabled in my signup flow, and guide me to connect my existing number.

Thank you.
