How to subscribe Fanout Consumer using .Net

Question

I am trying to create a .NET C# version of the Enhanced Fan-Out Consumer following the Java example provided in AWS's documentation. I am having difficulty converting the following Java version into .NET version. Can anyone help me with the equivalent code in C#?

KinesisAsyncClient client = KinesisAsyncClient.create();

SubscribeToShardRequest request = SubscribeToShardRequest.builder()
                .consumerARN(CONSUMER_ARN).shardId(SHARD_ID)
                .startingPosition(s -> s.type(ShardIteratorType.LATEST)).build();
