For context, web and mobile platforms require different underlying implementations, meaning a plugin that provides client-side functionality on the web is not necessarily supported on mobile as well.
If a plugin supports Native Mobile elements or actions, you will be able to access them from the elements tree or workflow tab in the Mobile app of your project. If you do not see this, it is likely that the mobile version of this is not yet supported by the plugin developer.
Mobile plugin development is still in the private alpha testing stage, meaning only select plugins support Native Mobile elements or actions at this time. You can read more about this in Josh's April Community Update, which lists some of the first plugins to receive Native Mobile support.
