Channel

Variable	Output
`{channel}`	Mention of the channel (same as `{channel.mention}`)
`{channel.mention}`	Mention of the channel
`{channel.name}`	Channel name
`{channel.id}`	Channel ID
`{channel.topic}`	Channel topic · empty if none

Useful in a rules card, where a button can point at the channel:

{container}{heading: Need help?}{content: Staff answer here.}{button: label: Open && url: https://discord.com/channels/{guild.id}/{channel.id}}

The channel is the one the message is sent in, so the same script reused across channels resolves to each channel separately.
