if a GuildMember is not connected to a voice channel you can't get him to join one ( I think), we can only move it from one voice channel to another,
can you add this feature?
why would I need this feature?
I did a bot with discord.js
when the user enter the command "!play fbi"
it opens a gif and send the sound of this video : https://www.youtube.com/watch?v=LO1Z8HOGeWo
it was a funny idea in my opinion xD
or when you enter the command "!play ok" it runs https://www.youtube.com/watch?v=GDTBXX2ZwUU
we can't launch a video directly, it was my solution
