Using separate authorization tokens for each federated GraphQL server

[m0hameen]

Hi,

I have a usecase where I have two GraphQL servers and I want to use federation to combine them. However both of them require different Authorization tokens. Can we perform authentication for both servers at the gateway level?

For example, GraqhQL Server 1 uses Authorization token A and GraphQL Server 2 uses Authorization Token B.
At the Gateway level we authenticate using token A, and if it succeeds we want to pass in the respective tokens to the servers(A to server 1 and B to server 2). Is something like this possible?
