    Had a simple answer by drinking a water and trying get my brain straight hahahaha

    this is the answer

    const result = roles.filter(
  (dt) => dt[1] === 'member'
);

    const roles = [ ['roles', 'admin', 'write'], ['roles' ,'admin', 'read'] ,['roles', 'member', 'read']]
const answer = roles.find(arr => arr.some((e) => e === "member"));
console.log(answer)

    If you want to return multiple arrays consisting the same string say "admin"
    use filter inplace of find in the above code
