How does uploading of images in messages work? The function WithFiles described in the docs doesn't appear to exist? #2260

I have local images I wish to upload with my bot as an attachment just like when I upload an image as a normal user via drag & drop. The docs say to use DiscordMessageBuilder and WithFiles ( https://dsharpplus.github.io/DSharpPlus/articles/beyond_basics/messagebuilder.html ) but this method doesn't seem to exist. Any help would be appreciated.
