Ahead of the Christmas holiday, Messenger released a “Christmas” chat theme that allows users to add a Christmas sweater background to conversations.

When this theme is activated, the conversation’s emoji will automatically be updated to the Christmas tree emoji. In addition, three word effects will automatically be added to the conversation for the words “tree,” “presents” and “Santa.”

Our guide will show you how to use the Christmas chat theme in the Messenger application.
