Problem with sending an email using the aqUtils.Email.Send() method.

Hi, I attempted to send an email using aqUtils.Email.Send(). Below I have mentioned that the code

function OnLogError(Sender, LogParams)
{
 // Check if the error is related to a test case failure
 if ( LogParams.MessageText = "An unexpected window has appeared.")
 {
   // Prepare email parameters
   var recipient = "recipient@example.com";
   var subject = "Test Case Failed!";
   var body = "The following test case failed: " + LogParams.LogMessage;

   // Send the email using Office 365 SMTP server settings
   aqUtils.Email.Send("smtp.office365.com", 587, "your_office365_username", "your_office365_password", recipient, subject, body);
 }
}

I get an error as "cannot read property 'send' of undefined."

Can somebody assist me in resolving the problem I'm having?
