Capable of set font for alert title and alert message however not for the Okay alert button.

Wish to set the font for the Okay additionally, Thanks upfront.

let alertController = UIAlertController(title: NSLocalizedString(title, remark: ""), message: NSLocalizedString(newErrorMessage, remark: "") , preferredStyle: UIAlertController.Type.alert)
            alertController.view.tintColor = UIConfiguration.DarkGreen!
            let titleFont = LanguageManager.boldFont(measurement: 17.0)
            let attributedTitle = NSAttributedString(string: NSLocalizedString(title, remark: ""), attributes: [NSAttributedString.Key.font: titleFont])
            alertController.setValue(attributedTitle, forKey: "attributedTitle")
            let messageFont = LanguageManager.regularFont(measurement: 12.0)
            let attributedMessage = NSAttributedString(string: NSLocalizedString(newErrorMessage, remark: ""), attributes: [NSAttributedString.Key.font: messageFont])
            alertController.setValue(attributedMessage, forKey: "attributedMessage")
            
            //Unable to set the font for OK button.
            let okFont = LanguageManager.boldFont(measurement: 16.0)
            let attributedOk = NSAttributedString(string: NSLocalizedString("Okay", remark: ""), attributes: [NSAttributedString.Key.font: okFont])
            alertController.setValue(attributedOk, forKey: "titleTextFont")
            
            alertController.addAction(UIAlertAction(title: NSLocalizedString("Okay", remark: ""), fashion: .default, handler: nil))
            current(alertController, animated: true, completion: nil)

I wish to set the customized font for the alert title, message and button.
