For context, only plugins specifically built to support native mobile will appear in the mobile elements panel or workflow tab.
If you're not seeing certain plugin elements or actions in the mobile editor, it likely means that those parts of the plugin aren't mobile-compatible yet.
While backend plugins, such as those making API calls, can still function in both web and mobile apps, client-side plugins may not work as expected if they haven't been built to support mobile apps.
With that said, our team is actively working on expanding mobile-compatible plugins available in the Marketplace. For now, we recommend utilizing native features as much as possible.
