Trying to restructure my map in order to see it as a Tree.

data :

{
  "FacebookAPI": [
    "TwitterAPI",
    "TiktokAPI",
    "TeslaAPI"
  ],
  "TeslaAPI": ["TwitterAPI"],
  "TiktokAPI": ["WhatsAppAPI"],
  "BitcoinAPI": [],
  "WhatsAppAPI": [],
  "GoogleAPI": [
    "FacebookAPI",
    "TeslaAPI",
    "TwitterAPI",
    "TiktokAPI"
  ]
}

expected output

{
  "GoogleAPI": [
    {
      "FacebookAPI": [
        { "TeslaAPI": { "TwitterAPI": [] } },
        "TwitterAPI",
        { "TiktokAPI": { "WhatsAppAPI": [] } },
      ]
    }
  ]
}

my goal is to calculate the depth of each parent item :

Example :

Google calls : Facebook + Tesla + Twitter + Tiktok + WhatsAppAPI => depth should be 5

Whatsapp calls : CryptoEndToEnd => depth should be 1

can anyone help me out.
