Can I add reactions to my Facebook comments and posts using Social Inbox?
Currently, you won't be able to add reactions to your comments and posts while using Social Inbox.
But, you can definitely add an image or a GIF while replying to these comments or posts.
While you hit your reply, you'll find the image and gif icon as shown in the below screenshot.
It's always nice to use images and gifs' to keep your audience engaged.
