how can I pass secure string parameter with invoke-expression

Hi
I want to pass parameter in another ps1 script and run this, but I have problem to send parameter
my code:
#loginWindow.ps1

 $userName=$var_txt_username.Text
   [SecureString] $password=ConvertTo-SecureString $var_txt_password.Password -AsPlainText -Force
   $myPath="$path\MainWindow.ps1"
   $window.Close()
   Invoke-Expression "$myPath $userName $password"
    
 ------------------------------------------------------
 #MainWindow.ps1
 param(
 [string]$userName ,
 [secureString]$password
 )

and my error :
Cannot process argument transformation on parameter 'password'. Cannot convert the "System.Security.SecureString" value of type
"System.String" to type "System.Security.SecureString".

Thank you for your help

Hi,

You can use the call operator &

 & $myPath $userName $password
