In Akka.NET (using Akka.Cluster), how to set up several seed nodes (Beacon) to know about each other?

If I want to have two Lighthouse seed nodes working on different computers, where everyone should know about the other, how to set it up? Despite the fact that I found mention of using multiple instances of Lighthouse and examined configurations without seed seed that use multiple seed nodes, I could not find an example of several seed nodes (in particular, Lighthouse) on separate PCs that know each other.

I currently have something like this, but I'm not sure if this is correct.

With the configuration of another instance, basically the same thing, but with these differences:

akka.remote:

public-hostname = "192.168.72.56"

akka.cluster:

    seed-nodes = [
  "akka.tcp://MySystem@192.168.72.56:4053"
  "akka.tcp://MySystem@192.168.72.55:4053"
] #manually populate other seed nodes here, i.e. "akka.tcp://lighthouse@127.0.0.1:4053", "akka.tcp://lighthouse@127.0.0.1:4044"
