Stickers cannot be added to Business WhatsApp[Android]

[AbdullahProgrammer426351]

When I try to add stickers on Business Whatsapp, a dialog opens and gives me an error :

There's a problem with this sticker pack and it can't be added to Business Whatsapp

And when I click ok
Another dialog appears with the message

Error with the Pack:
Permission denial : reading com.example.xxx.stickercontentprovider/metadata/2 from pid=7454, uid=10047 requires com.whatsapp.sticker.READ or grantUriPermission()

This is likely because you have not setup your ContentProvider correctly.

You can check the docs here to see how this is done in the sample app: https://github.com/WhatsApp/stickers/blob/main/Android/README.md#advanced-development
