When proper Firestore Unity support?

It's 2024, but it's still not possible to create multiplayer games with Unity.

Firestore still doesn't have Admin Unity SDK to use in Unity servers (most multiplayer games use Unity with "Dedicated Server" platform selected on their server side).

You already have a C# SDK (https://cloud.google.com/firestore/docs/create-database-server-client-library), what's left is to just port a couple of pieces, test it and it's done, why not do it?

P.S. If I'm wrong and it's possible to use https://cloud.google.com/firestore/docs/create-database-server-client-library in Unity, please guide me through how to fix this exception:
`Grpc.Core.RpcException: Status(StatusCode="Internal", Detail="Bad gRPC response. Response protocol downgraded to HTTP/1.1.")` (happens after `query.GetSnapshotAsync()`).
Or if there is another Firestore Admin SDK for Unity, please give me the link.
