How to customize paraformat plugin in aem
I need to customize paraformat plugin in aem. for example I want to add class attribute to h1,h2,h3,p tag. Below is the OOTB behaviour

<h1>Out-of-the-box (OOTB) plugins and their features cover many text editing use cases, but there will always be a need for customization.</h1>I want to have to class attribute something like below
<h1 class="xyz">Out-of-the-box (OOTB) plugins and their features cover many text editing use cases, but there will always be a need for customization.</h1>Is it possible to add class attribute without making any code change. for example I tried to add property in dialog like

but it is not picked. I guess there is no JS logic to read "class" property hence I tried to find a JS file and make a modification and I found plugin js - /libs/clientlibs/granite/coralui2/optional/rte/js/core/plugins/ParagraphFormatPlugin.js but here I dont see any place or logic to add class attribute.
