Buttons Identifier

Hai, 

I'm building a web application. There am embeding power bi.

I have created a button (dummy ) with an action and triggered the button to print the pbix page using react.js. It is working fine.

But while triggering the button, all the buttons are getting trigger and all the buttons are working as print button.

Is there any possible way to get unique id of a button, with that I can tell this button should do this work.

Thanks in advance,
