Powershell function to copy files by reading a JSON file

I'm trying to work on a Powershell function which will copy a few files from a source directory and paste them to the destination. The source directory, destination path and the name of the file to be copied is being read from a JSON file. The JSON file looks like this:

{
    "sourceFolder": "C:\\LaptopFiles\\SourceFiles\\",
"Alienware": {
    "files": [
      {
        "source": "AlienwareLatest",
        "destination": "D:\\AlienwareLaptop\\AlienwareFiles",
        "forceOverwrite": "true",
        "copying": {
          "files": [
            "appsettings.json",
            "web.config"
          ]
        }
      }
    ]
  },
  "Lenovo": {
    "files": [
      {
        "source": "LenovoLatest",
        "destination": "D:\\LenovoLaptop\\LenovoFiles",
        "forceOverwrite": "true",
        "copying": {
          "files": [
            "appsettings.json",
            "web.config",
            "version.txt"
          ]
        }
      }
    ]
  }
}

NOTE: I have a RegEx in place that ignore the double slashes in the json file so when it's loaded in Powershell, it gets the correct path and not one with 2 slashes.

The script that I am trying to work on should do the following:

  1. Note the sourceFolder.
  2. Add the sourceFolder to the source and then the name of the file in copying of each object in JSON to make a full path. (C:\LaptopFiles\SourceFiles\AlienwareLatest\appsettings.json).
  3. Copy the file from the above source path to the destination path written. So copy the file from for example C:\LaptopFiles\SourceFiles\AlienwareLatest\appsettings.json to D:\AlienwareLaptop\AlienwareFiles\appsettings.json.

But I can't seem to make it work and I'm failing to come up with a proper structure so that each file is placed where it belongs.

I've done this so far:

$jsonConfigs = (Get-Content -Path LaptopInfo.json -raw) | ConvertFrom-Json
foreach ($item in $jsonConfigs.psobject.properties) {
   
    $configs = $item.Value
    $config = $configs.files
    foreach ($_file in $config.copying.files) {
        $_destination = $config.destination + "\" + $_file
        $_source = $sample_configs + $config.source + "\" + $_file
        $Check_Sample_Files = Test-Path $_source
        if ($Check_Sample_Files -eq 'True'){
         ### Do the copyig operation here and overwrite the file if it already exists ####
        } 
     }
}
