body: <p>I made two react apps using create-react-app, but now I need to merge both apps as a single app. I need to link my second app with the first when a button is clicked in the first app. How can I do that?</p>
  <p>The first app has a login, signup and dashboard page.The second app has a form written in Solidity Blockchain. When I click 'Fill Details' button in Dashboard page, the second app form should be rendered!</p>
