Hi, I am trying to call the following API: https://graph.facebook.com/v20.0/{{WHATSAPP_BUSINESS_ACCOUNT_ID}}/message_templates

for creating WhatsApp carousel templates

I am using the same access token, which I have been using for other whatsapp call, but getting the following error

OAuth "Facebook Platform" "invalid_request" "Unsupported post request. Object with ID '382xxxxxxxxxx' does not exist, cannot be loaded due to missing permissions, or does not support this operation. Please read the Graph API documentation at https://developers.facebook.com/docs/graph-api"

Not sure what is wrong, tried giving all permissions. Can some one guide , what am I missing
