Invite the bot to your server and create a channel called #mojikopi.
In #mojikopi, tag the bot with custom emojis to copy them to your server:
DaemonXI: @Mojikopi :thinking_bread:
Mojikopi: Copied thinking_bread to this server: :thinking_bread:
This bot responds only in channels named #mojikopi, so create that channel and
gate it to mods/admins only if you don't want normal users adding their own
emojis.
