React router with Eui Framework integrating issue

Hello guys,
Thanks in advance brothers, I am trying to integrate EUI with react-router, kibana started successfully but I see nothing I am not sure if I am wrong or no

I used this topic: https://github.com/elastic/eui/blob/master/wiki/react-router.md#react-router-5x

#routing.js

Thanks!
RIDA

Hi, is this a custom plugin? Kibana is still using Angular routing at the top level, so you will need to mount your React app to the base Angular route, then React routing within the app should work normally. We do this for many of Kibana's licensed plugins, for example this code in License management: https://github.com/elastic/kibana/blob/master/x-pack/legacy/plugins/license_management/public/register_route.js#L94
