How to retrieve data from Health Services on Canvas Renderer?

Question

I'm trying to develop my skills in Kotlin and Android development by creating a watch face project. However, I've run into some difficulties with how to obtain heart rate and step data within a watch face.

I'm trying to use the PassiveListenerService to get this information from the smartwatch, but for some reason, I'm unable to retrieve the heart rate data. It seems that the onNewDataPointsReceived() function is never called, so I believe the problem is related to my listener, but I can't seem to identify it.

Here is my code:

AndroidManifest:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
