Need assistance in adding devlink to react app

Question

-I created react app using npx create-react-app

• created test components on webflow
• installed the devlink cli and and created a config file in the root directory of the react app.
• on the devlink documentation it uses nextjs and the is placed in the layout.tsx file.

My question is how do i do the similar thing for react? where do i put the element and how?
