How to Data attribute to paypal button (javascript sdk ), something like qa-id to help with testing.

We are using the paypal sdk to render buttons on the page. https://developer.paypal.com/sdk/js/reference/

We also wanted to add "Data" attribute to the paypal button that is being rendered by that iframe , something simple like a "qa-id"="paypal-button-click"  so we can use this for testing.
