How do I remove emojis in Conversations?
Select the Add a Reaction smiley face at the bottom of the post.
Select Add a reaction or the smiley face at the bottom of the post. A set of emojis—small icons that can provide a short-hand response to a post—will appear, with the current emoji highlighted. Select the highlighted emoji to deselect that icon. The emoji will disappear from the bottom of the post.
The emoji no longer appears.
Note: You can only remove emojis that you have added to posts.
