What could be the reason that my sample app is not showing the whatsApp integration content
1

I have create a sample app to test the whatsapp integration in the meta developer account and I have associated that with the business. Now I am unable to see the content of whatsapp as I have pasted the snapshot. This is the same issue even if i create the new app again. Can some one help me here to resolve this issue and let me know what could be the issue as well?
