I’m using this package to send messages on WhatsApp Business, but when i try to use it i get this error:

{"error":{"message":"Unsupported post request. Object with ID 'messages' 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","type":"GraphMethodException","code":100,"error_subcode":33,"fbtrace_id":"AZy2DQf7fRL003f1RJcY8Kf"}}

i tried changing the token many times and also switching phone number, what can i do?

Here’s what i did:
Added this to config/services.php:

'whatsapp' => [
        'from-phone-number-id' => env('WHATSAPP_FROM_PHONE_NUMBER_ID'),
        'token' => env('WHATSAPP_TOKEN'),
    ],

added application token and phone number id inside .env:

WHATSAPP_FROM_PHONE_NUMBER_ID=XXXXXX

WHATSAPP_TOKEN=XXXXXX

and then i created a notification class in laravel like instructions said and used the notification facade to send the message.
