## Remarks

Part of server data push, used by M-Files clients that open a push channel with
[OpenServerDataPush](https://developer.m-files.com/APIs/gRPC-API/Reference/MFiles.IRPCServerDataPush/OpenServerDataPush/index.md). Sends the client's
answer to a push request that expects one; `response_id` is the ID of that request.
