Ask for advice on how to set the style in the conditional statement

[VahidGarousi]

Hi, I hope you are well.
How can I set two different styles for a button in the correct or incorrect condition without overlapping styles?

    if (isChecked) {
                Paris.style(binding.btnPay).apply(R.style.Theme_PrimaryButton)
            } else {
                Paris.style(binding.btnPay).apply(R.style.Theme_SecondaryButton)
            }

The code above has a problem and does not change the whole style. It does not reset in principle and overlaps the styles
