I can't access JSON with JavaScript from FireBase

Question

I starting to use JSON , I got this problem

{
  "Usuarios" : {
    "1_Michelle" : {
      "datos" : {
        "afeccion" : "72",
        "lat" : "-0.2830356023921064",
        "lng" : "-78.55023108422756",
      }
    },
    "2_Javier" : {
      "datos" : {
        "afeccion" : "72",
        "lat" : "-0.2830356023921064",
        "lng" : "-78.55023108422756",
      }
    }
  }
}

I'm trying to save like this

var users=["1_Michelle","2_Javier"];
var lat = [123n,123n];
var lng = [123n,123n];

but The main problem that I got it's I can't access for the second entity that are Michelle and Javier , I was trying for each but it doesn't work idk why. This JSON I'm getting from FireBase Any help would be really appreciated and good rated ty

Imagine that JSON you have in data variable, then you can get these names with this

let names = Object.keys(data.Usuarios)

Then you will have these names in names
