Play separate audio files as a continuous playlist

I have created an app that storifies scientific research by asking researchers to respond to 4 separate questions.

You can see the result of this here:

Is there any way to add an audio player that plays all of the audio files in order on one click?

Thank you for your help! This community has helped me so much on my bubble journey!
