How to create audio play list

I want to create a play lists of music. How can I do it? I could not find a way to upload audio file from my local computer.

There’s currently not a way to package audio files as part of the app package, so you’d want to upload them to someplace in the Internet, then use the Download files flow function to make them available in the device’s local filesystem. After saving the downloaded files into e.g. an app variable, you can then use the Audio category flow functions to play them.
