Description

When the sample method is invoked with a channel type Forum (IForumChannel), it throws an error "Unknown channel type".
It doesn't throw any error when used in a post inside that same Forum.
The channel is not null, I debugged it to make sure.

This is my first bot using Discord-net so I might be doing something obviously wrong ? Sorry if that's the case.

Version

(Also checked with 3.10.0, same issue)

Working Version

After some digging I found this which doesn't contain Forum.
This is all guess work tho.
