In Google Nearby Connections API, is there any way to keep advertise on while the app is off?

I am trying to create an app where users can see the information of other users in a nearby area(30m). I decided to use Google Nearby Connections API(P2P_CLUSTER), as I want users to be able find other users, as well as be found by other users. In Google Nearby Connections API, would there be any way to keep advertise on so that when a certain user tries to discover other users nearby, other users would be discovered even when they do not have their apps on? Or would there be any other API better suited for this task?

I am using Android Kotlin and firebase.
