How does the auto-discovery work?

How does the auto-discovery tool in Nagios XI works?

When I supply a network ID to run on, let's say 10.10.182.0/24 .
it finds many Microsoft Windows machines as well as Linux servers.
I wanted to know how it works... Can I supply a root/administrator password to the NagiosXI and expect it to connect to each server it finds in the auto-discovery job and automatically install the relevant agent and configure some common checks?
Or does the auto-discovery only scans the supplied network.ID, nmap's it's findings and setting checks for each open port it finds?

I want to be able to supply a network.ID to scan and supply administrative username and password and to press go... and I'd want the result to be:
The NagiosXI will go through the list of servers it found, will connect to each one of them automatically using the administrative credentials I supplied and install the agent there so it would be ready for monitoring... is this doable with Nagios XI?

Auto-Discovery does not do installation and configuration, just discovery.

On the backend it runs the nmap tool to discover hosts and open ports:

nmap is not 100% accurate for various reasons, so it makes a best guess as to the OS and services running.
