I am trying to query the graphql endpoint for PublishablePublish in order to update sales channel for specific products, but I am getting Access Denied as a response.
The query runs fine If I try it on graphql app on shopify admin. However If I try it through postman, it doesn`t work.
This is due to the missing App scope 'write_publications', but I can`t find this option anywhere in order to update it.
Does anyone have a solution for this?
This scope is currently available only to private apps on the Shopify Plus plan. Doc link here.
