Emojis Properties
When users are reading other people’s posts, they can provide feedback using ‘Likes’. By default, they can choose from several Emojis: Love heart, Laugh, Shocked, Sad, Angry.
You can refine these options in the property pane. Likes can be turned off completely (note that ratings and voting could still be used). Or, you can have only the Love heart Emoji by setting Enable Other Emojis to off.
