How can I use the usemap attribute in MJML? I have seen in the documentation that exists but isn't always supported. I searched for some reference from which to start but I couldn't find anything
I tried this but don't work and I don't have any idea about how to continue
<mjml>
<mj-body>
<mj-section>
<mj-column>
<mj-image usemap="#mappa" width="350px" src="https://www.online-image-editor.com//styles/2014/images/example_image.png" />
</mj-column>
</mj-section>
</mj-body>
