Observer not working for sleep

[pateljenish32]

I have implemented three observer to get a trigger while any data has been added to healthkit, while app is in background. So for steps and workout it seems working fine. I am able to get trigger for it but not getting for the sleep data. Would you please let me know that am I missing anything in setup or it is expected behaviour or anything else needed to be add for sleep. I have implemented it like below.

It might be an underlying Swift issue actually, noticed basically all apps tracking sleep come with sleep notifications later during the day. For me sleep sync seems to trigger when I go into sleep in the Apple Health app.

If you have time to dig into this behavior - please let me know what you find! :)
