I want to add the custom field i.e. po_number in the braintree credit card method in the payment page. Here is the code which I have added for field.

                                                                </item>

                                            </item>
                                        </item>
                                    </item>
                                </item>
                            </item>
                        </item>
                    </item>
                </argument>
            </arguments>
        </referenceBlock>
    </body>
</page>
 

The field is coming but it is appearing for all the payment methods, but I only needs to be in the credit card method.

Any Help is appreciated.
