This is the error report:
e: C:\Users\Admin\Desktop\classified-native-android-app\main_files\Classapp\app\src\main\java\com\mycom\myapp\utills\OTPVerification.kt: (466, 45): Unresolved reference: id

Below is the line of code from the mentioned 466-477, it is also up there in the script.

 fun showDialog() {
        val view = layoutInflater.inflate(R.layout.verified_successfully_dialog, null)
        var button = view.findViewById<Button>(R.id.ok)
        button.setText(otpModel.phoneDialogStrings.btn_confirm)
        button.setBackgroundColor(Color.parseColor(SettingsMain.getMainColor()))
        button.setOnClickListener {
            finish()
        }
        val dialog = AlertDialog.Builder(this).setView(view)
        val alert = dialog.create()
        alert.setCancelable(false)
        alert.show()
    }```

Thanks.
