How to add html as icon on mapstore

[sai anand]

Hi Mapstore,

Can the HTML be added as an icon on top of mapstore? I saw it can done from Leaflet library but i haven't found any correct documentation for it. I'm able to do it properly in the Leaflet. Please see the sandbox link.

But it's not working with Mapstore

Thanks,
