Calling Framework7 from JavaScript

Playing around with Framework7 (mobile is my primary focus), I am trying to use some of the “not supported” components, however I struggle calling F7.

Found this post: Calling Framework7 function that helped a bit, but as it looks like, I can’t call all methods of the framework, e.g. creating Gauges as Framework7.instance.gauge.create() throws an error, while others, like Framework7.instance.actions.create() work.

Is there a reference to the F7 App that I can use?

Oops. Forgot to mention: @George @patrick @Teodor for the rescue?
