Background Music keep playing.

Hello. I heard about this workaround but have yet to try it:

A workaround for pausing the background audio for a specific slide when a video ends or is paused is to add another video to the slide. Configure the video as follows:

1. Make sure the video is short and has no audio.
2. Insert the video into the slide and drag it outside of the slide area so it is not visible to the learner.
3. Add a trigger to play the new video when your video completes.
4. Add a trigger to play the new video when the new video completes.

This will result in a hidden video playing outside the slide that starts when your original video ends and loops continuously during the slide. While this new video plays, the background audio will be paused if you enable the option under Slide-Related Settings to Pause background audio when video content plays on a slide.
