How to get list of devices connected to our mobile hotspot?

I am creating a mobile hotspot (access point) and connecting some devices (I am using 6 NodeMCU boards for this project; if you are into electronic you may know about NodeMCU). I need to get the list of devices (name & ip). I can’t able to find any info about it in community.

I did a deep research; what I found is there are extension to check about avilable wifi details. But nothing of handeling ‘Portable Hotspot’ stuffs.
