userReactionCallback in ReactionPopupConfiguration not triggered

[Soul199624]

Hi, i wanna ask why im not receiving any callback data. When I select an emoji reaction upon a long press. Idk if i did it right or I'm missing something. Thanks

reactionPopupConfig: ReactionPopupConfiguration(
userReactionCallback: (messageId, emoji) {
loggerNoStack
.i('User reacted on message: $messageId with $emoji');
},
shadow: BoxShadow(
color: isDarkTheme ? Colors.black54 : Colors.grey.shade400,
blurRadius: 20,
),
backgroundColor: theme.reactionPopupColor,
),
