❔ IAsyncEnumerable vs List<T> as parameter in method

I have a method that is overloaded and will take in a List<T> or IAsyncEnumerable. The method will batch requests up to 10 then send them. I am confident the List<T> version is doing what I expect. But I am unsure exactly what to expect with the IAsyncEnumerable 
await foreach (var message in messages)
        {
            var sqsMessage = JObject.Parse(message).ToObject<Message>();

            sendMessageBatchRequest.Entries.Add(new SendMessageBatchRequestEntry()
            {
                Id = sqsMessage?.MessageId,
                MessageBody = sqsMessage?.Body,
                MessageAttributes = sqsMessage?.MessageAttributes,
            });

            if (sendMessageBatchRequest.Entries.Count == batchSize)
            {
                failedMessages.AddRange(await SendMessagesAsync(sendMessageBatchRequest));
                sendMessageBatchRequest.Entries.Clear();

                if (_request.PublishingDelayInMs != null)
                {
                    await Task.Delay(_request.PublishingDelayInMs.Value);
                }
            }
        }
await foreach (var message in messages)
        {
            var sqsMessage = JObject.Parse(message).ToObject<Message>();

            sendMessageBatchRequest.Entries.Add(new SendMessageBatchRequestEntry()
            {
                Id = sqsMessage?.MessageId,
                MessageBody = sqsMessage?.Body,
                MessageAttributes = sqsMessage?.MessageAttributes,
            });

            if (sendMessageBatchRequest.Entries.Count == batchSize)
            {
                failedMessages.AddRange(await SendMessagesAsync(sendMessageBatchRequest));
                sendMessageBatchRequest.Entries.Clear();

                if (_request.PublishingDelayInMs != null)
                {
                    await Task.Delay(_request.PublishingDelayInMs.Value);
                }
            }
        }
The list T method is the same code but with foreach instead of await foreach.

I don't quite get the question, where are you still confused exactly?

List<T> does the same as AsyncEnumerable version (but asyncEnumerable is async) so, as Sossenbinder said, what r u questioning?
