Shazamkit for android is missing information.

Hi, dear apple developers.

Is there any full example about shazamkit for android developers? I've found that There is no full example about how to use shazamkit to build an android app propertly in WHOLE Internet(eg: github etc.)....

the documentation below is missing a lot of information. https://developer.apple.com/shazamkit/android/

Especially how to associate MediaItem with signature. https://developer.apple.com/shazamkit/android/shazamkit/com.shazam.shazamkit/-media-item/index.html

in swift we can use customCatalog.addReferenceSignature(signature, representing: [mediaItem])

but I can't see anything about it in kotlin

So, is there more information about it?
