I just:

1. Copied this repo, cd into folder
2. Changed roullupOption in vite.config.ts to:

rollupOptions: {
      external: ['react', 'react-dom', 'react-dom/client', 'react/jsx-runtime', '@tonconnect/ui'],
      output: {
        globals: {
          react: 'React',
          'react-dom': 'ReactDOM',
          'react-dom/client': 'ReactDOMClient',
          'react/jsx-runtime': 'ReactJSXRuntime',
          '@tonconnect/ui': 'TON_CONNECT_UI'
        }
      }

3. Ran yarn build
4. Copied the output folder (/dist if I recall correctly) into my project (I used /lib directory)
5. Import everything I need, like this:

import {
 useTonConnectUI,
 toUserFriendlyAddress,
 useTonWallet,
} from 'lib/ui-react'

PS: you may need to change tsconfig: "exclude": ["node_modules", "src/lib"]
