What is the spapi_oauth_code ?

I have allowed an app to a seller in beta.

https://sellercentral.amazon.com/apps/authorize/consent?application_id=amzn1.sp.solution.*************&version=beta&state=#

There are 2 pieces of information returned after confirming the application from the seller account.
One is the seller's id selling_partner_id and the other is the spapi_oauth_code.

How can I create a token with this information?
I want to access the user's inventory.

CLIENT_CONFIG = { "lwa_app_id": "******************", "lwa_client_secret": "*************************", "aws_access_key": "*******************************", "aws_secret_key": "*********************************************", "role_arn": "*****************************************", "refresh_token": "************************************" }

res = Products(credentials=CLIENT_CONFIG, marketplace=Marketplaces.US).get_listings_offer(seller_sku='CD-R0E2-I3TI',item_condition='New')
    print(res)
