Which Mux Elements/Packages would you like a new feature for?

• I'd like to propose a new Element!

🎥 Describe the feature you'd like to request

I would like propose a new element that can display the current views for a video tracked by Mux Data. The element could show current views or unique viewers (we'd probably want unique viewers by default but it could be configurable) and update about every 30 seconds to provide customers with an constant, up-to-date count that can be displayed for viewers or related users.

💻 Describe the use cases the feature will solve

As a developer that is building an education platform, I want to help the instructor to know how many people are on the class throughout the stream so they know what in their content is working well (or not) and whether they are gaining or losing viewers.

As a developer of a concert app, I want to show the attendees how many people are attending in order to drive more interest and demonstrate how great the artist is.

⭐ Describe the solution you'd like to see

I'd like an real-time count element that a developer could drop in their application, which takes care of all the bookkeeping and mechanics of calling the engagement counts API.

🔄 Describe alternatives or workarounds you've considered

The alternative is for the developer to manage calling the API and building the widget themself. Doable but harder than it if there was an element.
