react-dom.development.js:86 Warning: You are calling ReactDOMClient.createRoot() on a container that has already been passed to createRoot() before. Instead, call root.render() on the existing root instead if you want to update it

Upgrade your react to be version 18.x.x or use react-confirm-alert version 2.x.x for react <= 17.x.x

About this warning (You are calling ReactDOMClient.createRoot() on a container that has already been passed to createRoot() before.), it seems to be caused by React's strict mode (index.js file), which mounts the component 2 times at a time to do checks. It would have no other consequences.
