Describe the domain model extension

First of all, thanks for providing us with a great library.
What we would like to do is update the body of messages sent to Teams and reply to them.

Due to the current SDK specification, there is no way to retrieve Teams messages by themselves,
First, a list of messages must be retrieved, and then the messages must be filtered to update the body of the message and reply to it.
ex) Getting Chat Message replies

channel = await channel.GetAsync(o => o.Messages);
var chatMessage = channel.Messages.AsRequested().FirstOrDefault();// must be load all messages

// Get the replies
var replies = chatMessage.Replies;

If there are a large number of messages in the channel, the API call will take a large amount of time (even if only one reply is written) because the body of the message cannot be updated or replied to without first reading the entire volume of messages.
Therefore, please implement a model for retrieving messages by themselves, specifying the message ID and reply ID.

We have considered the following method implementations, but you are free to change them if you find a more suitable form or implementation location

// get a message
ITeamChatMessage single_message = PnPContext.Team.Channels.GetByDisplayName("General")
.GetByMessageId("id_of_message");// and load ITeamChannel.Messages

//update message(exists method)
single_message.UpdateAsync();

// get a reply
ITeamChatMessageReply single_reply =  single_message
.GetByReplyId("id_of_reply");// and load ITeamChatMessage.Replies
