MegaGame support - Action Card Sabos

Discord can show a maximum of 25 reactions to a post, which is problematic for showing "No Sabo" reactions to an action card being played.

For games with 25+ players, I propose: editing the AC play message to show a list of emojis who have reacted, as well as a list of emojis we are waiting for. I believe we store the AC messageID already for tracking sabos internally, just need to edit/display on the original message.

Maybe an /ac sabo_status command which accepts a messageID
