How to add VBA code to Excel worksheet using PowerShell?

Question

I need to include a Private Sub Worksheet_BeforeDoubleClick (ByVal Target As Range, Cancel As Boolean) in my Sheet(1).

I'm able to open and write in cells.

$excel = New-Object -ComObject Excel.Application
$workbook = $excel.Workbooks.Add()
$worksheet = $workbook.WorkSheets.item(1)
$worksheet.range("c1","g6").value = "str"
...
$workbook.SaveAs($xlFlie, 50)
$Excel.Application.Quit()

How do I put the VBA code in the sheet (rather than in a VBA module)?

I tried this:

$xlmodule = $workbook.VBProject.VBComponents.Add()
$xlmodule.CodeModule.AddFromString($code)

I got this error:

Can not call a method in an expression Null.
Au caractère .\Build-ADGrpsMembers2Excel.ps1:273 : 5
+ $xlmodule = $workbook.VBProject.VBComponents.Add(1)
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I need to change VBA option to

$excel = New-Object -ComObject Excel.Application
New-ItemProperty -Path "HKCU:\Software\Microsoft\Office\$($excel.Version)\excel\Security" -Name AccessVBOM -Value 1 -Force | Out-Null
New-ItemProperty -Path "HKCU:\Software\Microsoft\Office\$($excel.Version)\excel\Security" -Name VBAWarnings -Value 1 -Force | Out-Null

my working code is :

$excel = New-Object -ComObject Excel.Application
New-ItemProperty -Path "HKCU:\Software\Microsoft\Office\$($excel.Version)\excel\Security" -Name AccessVBOM -Value 1 -Force | Out-Null
New-ItemProperty -Path "HKCU:\Software\Microsoft\Office\$($excel.Version)\excel\Security" -Name VBAWarnings -Value 1 -Force | Out-Null

$workbook = $excel.Workbooks.Add(1)
$worksheet=$workbook.WorkSheets.item(1)

$excel.Visible=$true
$excel.DisplayAlerts = $true
$excel.ScreenUpdating = $true

#$worksheet.range("c1","f6").ColumnWidth = 4
#$worksheet.range("c1","f6").Orientation = 90

$xlmodule = $workbook.VBProject.VBComponents.item('feuil1')
$code = @"
Private Sub Worksheet_BeforeDoubleClick(ByVal Target As Range, Cancel As Boolean)
End Sub
"@

$xlmodule.CodeModule.AddFromString($code)

$saveName = "$([Environment]::GetFolderPath('desktop'))\Export-Excel ($( ((Get-Date -Format u ) -replace ":", ".") -replace "Z", '' ) ).xlsb"

# savegarde du fichier
$workbook.SaveAs($saveName, 50)

Write-Verbose "Closing $($WorkSheetName)"
$Excel.Workbooks.Close()
Write-Verbose "Exit Excel"
$Excel.Application.Quit
