How do we render our custom app inside the react native rocket chat app?

Hi Guys, We are using this command in our web app which renders a custom app when a command is executed. But it doesn’t render anything in the app.

await modify.getUiController().openContextualBarView(blocksData, { triggerId }, user);

Would it make a difference if we use openModalView instead of openContextualBarView? If not, what is a good way to executing the custom app in the react native app.
