How to change UIAlertController height?

I found you can add constraints before you present the view controller

 let alertController = UIAlertController(title: nil, message: "hello", preferredStyle: .alert)
    
    
    let cancelAction = UIAlertAction(title: "Cancel", style: .cancel) { (action) in
        // hide action sheet
    }
    alertController.addAction(cancelAction)
    
   
    var height:NSLayoutConstraint = NSLayoutConstraint(
        item: alertController.view, attribute: NSLayoutConstraint.Attribute.height,
        relatedBy: NSLayoutConstraint.Relation.equal, toItem: nil, 
        attribute: NSLayoutConstraint.Attribute.notAnAttribute, 
        multiplier: 1, constant: self.view.frame.height * 0.80)
    alertController.view.addConstraint(height);
    self.present(alertController, animated: true, completion: nil)

Since I did not have a message to input I added lines with "\n \n \n" in the message field to make the alert controller height longer.
