From PowerShell Get Refresh History In Group from Power BI REST APIs and export do CSV

Question

I'm trying to get the PowerBI update history through the API URL through Powershell and export do CSV, I don't know much about Powershell but I'm trying to learn, since it's being very useful in the BI area where I work, I've tried to run the code through this site POWERBI SCHEDULED REFRESHES IN YOUR ORGANIZATION and also tried to edit to extract but with no success.

The site script runs without errors but does not return any results in CSV, is it because the URL is wrong?

Website script:

$myCred = Get-Credential
Connect-PowerBIServiceAccount -Credential $myCred

$Workspaces = Get-PowerBIWorkspace
$ExportFile =  "D:\Users\F02579\Documents\PowerBIRefreshHistory.csv"
Remove-Item $ExportFile -Force -ErrorAction SilentlyContinue

foreach($workspace in $Workspaces)
{

    $DataSets = Get-PowerBIDataset -WorkspaceId $workspace.Id | where {$_.isRefreshable -eq $true}
    foreach($dataset in $DataSets)
    {

        $URI = "groups/" + $workspace.id + "/datasets/" + $dataset.id + "/refreshes"
        #$OutFile = $ExportFolder + '\' + $workspace.Name + '-' + $dataset.Name + '.json'
        $Results = Invoke-PowerBIRestMethod -Url $URI -Method Get | ConvertFrom-Json

        foreach($result in $Results.value)
        {
            $errorDetails = $result.serviceExceptionJson | ConvertFrom-Json -ErrorAction SilentlyContinue

            $row = New-Object psobject
            $row | Add-Member -Name "Workspace" -Value $workspace.Name -MemberType NoteProperty
            $row | Add-Member -Name "Dataset" -Value $dataset.Name -MemberType NoteProperty
            $row | Add-Member -Name "refreshType" -Value $result.refreshType -MemberType NoteProperty
            $row | Add-Member -Name "startTime" -Value $result.startTime -MemberType NoteProperty
            $row | Add-Member -Name "endTime" -Value $result.endTime -MemberType NoteProperty
            $row | Add-Member -Name "status" -Value $result.status -MemberType NoteProperty
            $row | Add-Member -Name "errorCode" -Value $errorDetails.errorCode -MemberType NoteProperty
            $row | Add-Member -Name "errorDescription" -Value $errorDetails.errorDescription -MemberType NoteProperty
            $row | Export-Csv -Path $ExportFile -Append -Delimiter ';' -NoTypeInformation
        }

    }

}

I tried to put the URL that Microsoft provides in this link, but also without success.

My script:

Import-Module MicrosoftPowerBIMgmt.Admin

Connect-PowerBIServiceAccount -Credential $myCred

    ForEach ($dataset in (Get-PowerBIDataset -Scope Organization -WorkspaceId $workspace.Id))

            #$URI = "groups/" + $workspace.id + "/datasets/" + $dataset.id + "/refreshes"

After making some calls with Microsoft, with some engineers that works with PowerBI and Powershell conector, I'm now able to get those information.

Powershell script:

$authUrl = "https://login.windows.net/common/oauth2/token/"
$clientId = "Your clientID"
$pbiUsername = "Your user email"
$pbiPassword = "Your password"

$body = @{
    "resource" = “https://analysis.windows.net/powerbi/api";
    "client_id" = $clientId;
    "grant_type" = "password";
    "username" = $pbiUsername;
    "password" = $pbiPassword;
    "scope" = "openid"
}
$authResponse = Invoke-RestMethod -Uri $authUrl –Method POST -Body $body

$DatasetID = "Your datasetID"
$restURL = "https://api.powerbi.com/v1.0/myorg/datasets/$DatasetID/refreshes"

$headers = @{
    "Content-Type" = "application/json";
    "Authorization" = $authResponse.token_type + " " + $authResponse.access_token
}

$restResponse = Invoke-RestMethod -Uri $restURL –Method GET -Headers $headers | Select-Object -ExpandProperty value
$restResponse
