If the user is ignoring your box, you may wish to close it after a number of seconds. There’s an app for that. From the profile menu top right, click on Custom JS (Apps).
Install the app “Box Auto Close”, one time.
Now, any boxes configured with Widget metadata “auto_close_secs” will automatically close after the configured number of seconds if there is no user interaction with the box.
This is “box-level” metadata, in the Box Editor under the Widget accordion.
