Message not returned from Http::create_forum_post_with_attachments

[TheKodeToad]

The function returns the created channel, but not the message. Same applies to helper functions like ChannelId::create_forum_post etc.. According to the documentation this is returned nested in the channel object: https://discord.com/developers/docs/resources/channel#start-thread-in-forum-or-media-channel.

Rough suggestion on how to represent this (means breaking change I suppose)

struct GoodStructName {
    channel: GuildChannel,
    message: Message,
}

Just to give an example of why this might be useful:
My usecase is a modmail bot - when a user sends a direct message to the bot, it reposts it in a forum channel. I am trying to make this message update to reflect the source message upon edits by storing a relationship between the source message <-> reposted message - and to do this I need the message ID.

I found out that the thread and starter message ID are actually the same. So while this could be done, it's not that useful.
