Implementing React.js application

I have a react app that is a web page and should open when clicking on the plugin button in the top panel. I compiled it into js and css files. Also added a file with the config. I tried to make a zip archive with the .plugin extension out of all this. But an error occurs when adding. Can you tell me what settings I need to make for it to start working? Perhaps the plugin methods are missing.

Hello,
The React application should be integrated with Document Server as in this example here to work properly: ONLYOFFICE Docs React component - ONLYOFFICE Api Documentation
Please check and make sure you did it accordingly
Or do you mean that you are actually trying to add a React.js plugin to Document Server itself?

I am trying to make something like Telegram example but instead of telegram web page i want to use compiled version of a react application (dist folder with index.html and assets)
