But I think that having it done only using HotChocolate services would be better and will not introduce some apollo proxy for just combining schemas, so you could try this tutorial https://chillicream.com/docs/hotchocolate/v10/stitching
They differ in details and integration part, you could try both and choose best option for you I don't have ready answers because also need to check it out more.deeply in future
Yeah, something like that It combines different schemas together and after that it could be used as a single entry point for your distributed API across different GraphQL servers
