Notification badge in React js ?

first we have use the react-icons BsFillBellFill then we have use the badge from the react-bootstrap

checkout the import statement and how to use them

import { Badge } from 'react-bootstrap'

import { BsFillBellFill } from 'react-icons/bs'

<BsFillBellFill size={30} />
            <Badge pill variant='primary'>
              3
            </Badge>

now we just have to call the service and get the count and show in the Badge component.
