Как найти объект в массиве?

import React from 'react'
import { useSelector } from 'react-redux';
import { useParams } from 'react-router-dom';

export default function User(props) {
  const { gistName } = useParams()
  const gists = useSelector(state => state.gists.data)

  const item = gists.find(item => item.files.`${gistName}`.filename === gistName);
  console.log(item)

  return (
    <div>
      
    </div>
  )
}
