How to avoid the warning: Warning: ReactDOM.render is no longer supported in React 18. Use createRoot instead. Until you switch to the new API, your app will behave as if it's running React 17. Learn more: https://reactjs.org/link/switch-to-createroot

I am new to Ignite and wondering that how can I resolve this warning message. I tried few things but it seems like ReactDOM is controlled by react native library and we cannot change it through Ignite boilerplate. Please suggest the solution for this problem.

index.js:1 Warning: ReactDOM.render is no longer supported in React 18. Use createRoot instead. Until you switch to the new API, your app will behave as if it's running React 17. Learn more: https://reactjs.org/link/switch-to-createroot.

Also getting this warning:
index.js:1 WebSocket connection to 'ws://localhost:9090/' failed:

Any help would be appreciated.

Thank you
