PSObject nested iteration over multiple properties

Question

Let's say I have an array of PSObjects with several properties that are hierarchical. Something like

@{
   'city' = 'CityName'
   'street' = 'StreetName'
   'House' = 'NNN'
   'Apartment' = 'MMM'
}

How do I do nested iteration over these properties? Like, city first, then street etc.?

City A
- Street a
  - House 1
    - Apartment 1
    - Apartment 2
  - House 2
    - Apartment 1
    - Apartment 2
- Street b House 1

... etc...

What comes to mind either create lists of unique values for each property and then iterate through them filtering corresponding objects, or use multiple Group-Objects?

@zett42 Yeah, I saw that post and no, it doesn't answer. It iterates through all properties, while I need to iterate nested according to hierarchy. I figured this out - see my answer. — miguello, Dec 09 '20 at 20:43

foreach($groupCity in $myObject | Group-Object 'city')
   Write-Host($groupCity.Name)
   foreach($groupStreet in $groupCity.Group | Group-Object 'street'){
      Write-Host($groupStreet.Name)
      <#and so on...#>
   }
}
