GraphQL – Edit Schema – Microsoft Fabric Community

I need to edit my schema to be able to load data using pagination using GraphQL in Fabric. 

In Microsoft Fabric, you cannot directly modify the GraphQL schema via queries. The Schema Explorer in Fabric is read-only, and schema modifications need to be done in the GraphQL server’s codebase but I can’t find where to the neccessary changes to the schema. For example I need to be able to add: 

type PageInfo {
  endCursor: String
  hasNextPage: Boolean
}

Any help would be really appriciated. Regards Frans
