How to detect incoming video call from from ZegoCloud when app is closed or when chat activity is destroyed?

Question

I'm trying to use ZegoCloud to add audio & video call features, and it's working fine while the sender and receiver are in the same activity (Chat Activity). But, when the receiver is on another activity, the app in background or the app is closed, the incoming call is never detected and the incoming call activity is never shown. Below is the android manifest with incoming call service.

Thank you..
