How can I add URL buttons/reactions to my posts?

The Controller Bot Team

While creating new post, choose 'Add URL Buttons' or 'Add Reactions' under a message preview. You can combine reactions with URL buttons — emoji like-buttons will be displayed above them.

Make sure to include http:// or https:// in your URLs when you add them to the list of URL buttons.
