Challenge: Applying Nullable Types

Overview

Using the project below, perform the tasks highlighted in the requirements section.

Requirements

The code widget below contains Protobuf files with all message fields defined as scalar value types, which are not nullable. We will need to convert all the fields in the ChatRequest and ChatReply into their nullable equivalents. We'll need to do it both in the BasicGrpcClient and BasicGrpcService project. After it's done, we must make any additional code changes to ensure it still compiles and runs.
