This controls whether Leg will respond to reactions on Karuta embeds, even if Leg didn't add the reaction himself (either because reaction_shortcuts is off, because you/your server doesn't have Premium, or because someone already used reaction shortcuts on the message before)
Enabling this feature can cause disasters if your server has third-party bots with reaction capabilities (e.g. Keqing).
Additionally, you should consider using channeloverride this feature to off if you have announcement channels where users can add reactions.
The moneybag emoji is an example of a Reaction Shortcut for "leg price"
