Wrong access level in trait

[Nks]

Inside trait we have
/** * The data to sync to QuickBooks. * * @see https://developer.intuit.com/docs/api/accounting * @return array */ abstract protected function getQuickBooksArray(): array;

But inside interface we have

public function getQuickBooksArray();

Then it cause the error:

Access level to LifeOnScreen\LaravelQuickBooks\QuickBooksEntity::getQuickBooksArray() must be public (as in class LifeOnScreen\LaravelQuickBooks\QuickBookable)

I have the same issue.
I think that getQuickBooksArray method should be only in the abstract class because the methods in the Interface are public contact, the protected methods corresponding to internal functionality.
