Issue with using Xrm.Utility.openQuickCreate() from HTML web resource

I'm trying to open an entity's Quick Create form from an HTML web resource from navigation of an entity. I'm using Xrm.Utility.openQuickCreate("entityname", null, null) for a start.

I get an error saying JQueryApi is not defined in the browser's console.

However, other functions like Xrm.Utility.openEntityForm and Xrm.Utility.isActivityType(entityname) does work.

Any suggestions? Thanks.
