Hey, what's up.

I'd like to ask why some resources are hidden.

And we some bugs.
For example,
On customer creation
Undefined column: 7 ERROR: column "phone" of relation "customers" does not exist

On coupon creation
Class "App\Nova\OrderPurchase" not found
R64\Checkout\Models\Coupon::orders()

On orders, again
Class "App\Nova\OrderPurchase" not found
