Rename the root Query, Mutation, and Subscription elements

Product

Hot Chocolate

Is your feature request related to a problem?

I'm trying to use Fusion to merge an external graph (run by Hasura) that defines root elements as query_root, mutation_root, etc.

Fusion cannot merge the definitions of the graphs because the root elements in Hasura and Hot Chocolate are not the same. The Hasura graphs can't be changed (existing deployments), so I wanted to change the Hot Chocolate graphs to use the Hasura root element names.

I have tried everything and cannot get the exported schema to use query_root, mutation_root, etc.

The solution you'd like

I should be able to do something like [QueryObject(Name="query_root")] and have that reflected in the schema.

If that's not possible, maybe a way for Fusion to be able to rename root elements for external graphs?

The issue names no files, tests, or entry points to inspect. Start by locating the Hot Chocolate schema-generation code for root Query, Mutation, and Subscription types; done means an agreed mechanism lets exported schemas use names such as query_root, mutation_root, and subscription_root for Fusion compatibility.
