Create channel message
The Create channel message block is used to send a message to a specific channel.
You can either configure the message in the block directly or use a message template instead. In both cases you can add embeds, components v2 layouts, and interactive components to the message. The only case where it's better to use a message template is when you want to use the same response in multiple places.
To send the message as a reply, set Reply To to the ID of a message in the same channel, like {{message.id}} in a message event listener.
If the message contains interactive components, the flow will be suspended until the user interacts with the message. See Sub-Flows for more information on how interactive components work.
In the blocks attached to a button or select menu, user is whoever clicked it. Use origin.user for the person who ran the command. See Who is user in a sub-flow?.
