app doesn't work in IE 11

[chl8725]

I tried dev/demo
import'../node_modules/react-app-polyfill/ie9.js'; // For IE 9-11 support
import'../node_modules/react-app-polyfill/ie11.js'; // For IE 11 support
import'../node_modules/react-app-polyfill/stable.js';
As above, polyfill was installed and imported.
I added ie to browserlist also in package.json file
But it comes out like the picture below. What should I do?

Please tell me

IE9 is not supported, for IE11 you need to import CSS:

What you said is " import'react-chart-editor/lib/react-chart-editor.ie.min.css' "?
What file should I put in this sentence?
I put it in the index.html file but it didn't work

I don't know where this file is react-chart-editor.ie.min.css. Where are you? Please let me know
