No '+ Add a tile' option visible

I'm looking to add a widget to a power bi report. I've found a few articles explaining how to add web content to a dashboard using the '+Add a tile' option from the Power BI online service.

What I am supposed to see:

However, I do not see the '+Add a tile' option or even the 'Edit' dropdown. All I have is an 'Edit' button which when pressed opens the editor. I've tried finding the option using search box and combing through the visuals pane and the ribbon. I even tried another route with the HTML viewer custom visual in desktop but that came with its own problems.

Also, I'm using gov.us but I'm not sure whether that has anything to do with the issue.

For reference, here is the widget code I'd like to use: 

div class="embedsocial-forms-iframe" data-ref="71104d53274b4f2bc8c8d7cb555a66f367abb5ca" data-widget="true" data-height="auto"></div><script>(function(d, s, id){var js; if (d.getElementById(id)) {return;} js = d.createElement(s); js.id = id; js.src="https://embedsocial.com/cdn/ef.js"; d.getElementsByTagName("head")[0].appendChild(js);}(document, "script", "EmbedSocialFormsScript"));</script
