+In the `exec` method we insert the current time into the editor.
+At the same time, if we disable the plugin, the button will disappear from the list.
+
+Note that after insertion we call the `synchronizeValues` method, which synchronizes the values between the textarea and the editor.
+
+This is necessary for the history module to work correctly, since the editor does not use [MutationObserver](https://developer.mozilla.org/en-US/docs/Web/API/MutationObserver) to track changes internally.
+
+> We may move to [MutationObserver](https://developer.mozilla.org/en-US/docs/Web/API/MutationObserver) in the future, but until that happens, you need to call `synchronizeValues` yourself after inserting content to the editor.
