Payment Gateway Adding

[アミラ]

I have requested access for developing a payment app. And I received approval. But I do not have access to major scopes. It gives the following error when requesting the scopes during the oauth stage.

Can you provide access to the following scopes? 

write_payment_settings, read_payment_settings
