Working with GraphQL's ShopifyPaymentsAccount object

[shooter0106]

Hello!

I'm trying to use an `QueryRoot.shopifyPaymentsAccount` resource to get linked PayPal account credentials(`client_id` token and others).  This documentation page https://shopify.dev/docs/admin-api/graphql/reference/object/shopifypaymentsaccount described an `ShopifyPaymentsAccount` object. Note at this page says that my application need to use a `read_shopify_payments` approval scope.
But every time i try to authorize my app with them i get an error:

Without this scope i get a access denied error on `QueryRoot.shopifyPaymentsAccount` resource.

So, what i'm can done with this? Is there a way to use this API? Or maybe Shopify provides another way to solve this problem?

Or maybe i do not need a PayPal credentials, and Shopify have a another way to receive payment from customer? Without default checkout interface.

Please note, my application is not a sales channel, i can't use a Storefront API.
