gRPC doesn't seem to generate client side code needed for accessing service - asp.net-core

Question

I am exploring gRPC by downloading and following the PortfoliosSample from here.
The sample code are all working fine. When I tried to create my own simple service and client by following the sample, however, I noticed that the generated code on the client side doesn't include the class and functions needed for accessing the service.
In the PortfoliosSample, the client side code generated based on the portfolios.proto includes and class named PortfoliosClinet (in PortfoliosGrpc.cs)
public partial class PortfoliosClient : grpc::ClientBase<PortfoliosClient>
Various functions (such as Get, in the class) are available for client side program to use for invoking the service.
In my generated code, BrokerGrpc.cs, there is no "GroupClient" class or anything similar in it. As a result, my client side code cannot use the generated code to access the service. What am I missing?
Here is the TSAPIBroker.proto file defined on the server
syntax = "proto3";
option csharp_namespace = "Test.API.TSAPIBroker.Protos";
package TSAPIBroker;
message Group {
int32 id = 1;
string name = 2;
}
message Groups {
repeated Group group = 1;
}
message GetRequest {
int32 groupId = 1;
}
message GetResponse {
Group group = 1;
}
service GroupService
{
rpc Get(GetRequest) returns (GetResponse);
}
And here is the generated TSAPIBrokerGrpc.cs

Using the container image mcr.microsoft.com/dotnet/sdk:5.0, I'm able to use your proto to generate both files:
TSAPIBroker.cs
TSAPIBrokerGrpc.cs
Repro:
dotnet new console
dotnet add package Grpc --version 2.33.1
dotnet add package Grpc.Tools --version 2.33.1
dotnet add package Google.Api.CommonProtos --version 2.2.0
Reference your proto from ther project file and then build.
My generated *Grpc.cs contains GroupServiceClientclass.
NOTE the message Groups is defined but not used.
