Syncing of audio file while doing Lottie animation

Hello Everyone,
I’ve created an animated Christmas card using a Lottie animation and the Slider. Each slide moves the single Lottie animation to a different time stamp, and it works ok. I’d really like to add some sound effects to it, so do you know if there’s any way of syncing an audio file, that can also be controlled by the slider using custom animations? Ideally it would do the same as the Lottie file - time stamp at different places so it’s just one file to load rather than having 24 separate audio files.

I’m really keen to use this platform to create interactive picture books, but really need to get the audio working to bring them to life.
Thanks in Advance
