+      <Description>
+        The MessageThread component supports lazy loading for the rich text editor used for editing messages. This means
+        that the rich text editor and its dependencies can be excluded from the bundle if they're not required,
+        utilizing tree-shaking techniques such as [the sideEffects
+        option](https://webpack.js.org/guides/tree-shaking/#mark-the-file-as-side-effect-free) in webpack.
