I have created an Meta app which can used to Send WhatsApp Message.

I have registered my WhatsApp number. but I am not able to send whatsapp message.

When I am sending whatsApp message I am getting error Unsupported post request. Object with ID '44231XXXXXXX' does not exist, cannot be loaded due to missing permissions, or does not support this operation. Please read the Graph API documentation at.

Any help can be appriciated.
