Question
This hole article says to use "channel.send" but dont you need to use "message.channel.send"?

[almostSouji]

<Message>.channel is just one way to gain access to a channel (the channel the source message was posted in).

You can also retrieve channels from the guild cache <Guild>.channels.cache or the client cache <Client>.channel.guild or in the context of a reaction event <MessageReaction>.message.channel, on channel creation client.on("channel", channel => ...), to name some examples.

Explaining any and all means by which you can get a channel would take way too much place, and the focus of this guide section is how to compose and send an embed, not how to get the channel from to send it in.
