Adding additional text in mail from script

Hi,

Small question, I have created a custom datasource that uses a embedded powershell script:

# Variables
$Folder = '##ps.filecount.folder##';
$Minutes = '##ps.filecount.minutes##';
$Recurse = '##ps.filecount.recursive##';
$Exclude = '##ps.filecount.exclude##';
$ComputerName = '##system.displayname##';

# Build parameters dynamically
$GetChildItemParams = @{
    Path       = $Folder
    Attributes = '!Directory+!System'
}

if ($Recurse) {
    $GetChildItemParams['Recurse'] = $true
}

# Create session dynamically
$Session = New-PSSession -ComputerName $ComputerName

try {
    # Execute remotely
    $Result = Invoke-Command -Session $Session -ScriptBlock {
        param (
            $Folder,
            $Minutes,
            $Recurse,
            $Exclude,
            $GetChildItemParams
        )

        if (-not (Test-Path $Folder)) {
            # Exit with special error code if folder missing
            exit 3
        }

[array]$Files = Get-ChildItem @GetChildItemParams |
    Where-Object { $_.LastWriteTime -le (Get-Date).AddMinutes(-$Minutes) -and $_.FullName -notmatch "$Exclude" -and $_.FullName -notmatch "nagios-monitoring" -and $_.FullName -notmatch "netscaler-monitoring" }

# Get the newest file among all (not just those older than $Minutes)
$NewestFile = $Files | Sort-Object LastWriteTime -Descending | Select-Object -First 1

# Safely extract properties
$NewestFilePath = if ($NewestFile) { $NewestFile.FullName } else { "" }
$NewestFileDate = if ($NewestFile) { $NewestFile.LastWriteTime } else { "" }

# Return both count and newest file path
return @{
    Count       = $Files.Count
    NewestFile  = $NewestFilePath
    NewestDate  = $NewestFileDate
}
    } -ArgumentList $Folder, $Minutes, $Recurse, $Exclude, $GetChildItemParams

    # Output only the final datapoint in the correct format
    Write-Output "NumberofFiles=$($Result.Count)"
    Write-Output "NewestFile=$($Result.NewestFile -replace '\\', '\\')"
    Write-Output "NewestFileDate=$($Result.NewestDate)"
    Write-Output "INFO: Found $($Result.Count) file(s) older than $Minutes minutes in $Folder on $ComputerName"
}
catch {
    # Optional: Output something recognizable for LogicMonitor if there's an error
    Write-Output "NumberofFiles=-1"
    Write-Output "NewestFile=ERROR"
    Write-Output "NewestFileDate=ERROR"
}
finally {
    # Cleanup the session (always!)
    if ($Session) {
        Remove-PSSession -Session $Session
    }
}

The Graph is fine (NumberofFiles), but I also want to include the "NewestFile" and "NewestFileDate" output in the mail alert.

is this possible?
