How to fetch with Axios using Env secret key – Javascript

I’m trying to fetch data from the Middleware API and am using A secret key to Secure the API.

But when I try to fetch the data it just doesn’t recognize the Secret params,

How can I make it fetch the data and make my secret key Secret.

.env.local

LOCAL_API_KEY=5b45f6898634abf9c3769b763c5fa8ddfc57d2cc943a0601f7bda4269ebe7342

updateUser.js

const {data: session} = useSession()
    useEffect(() => {
        if(session){
            const checkUserInfo = async() => {
                try{
                    const fetchUserInfo = await axios.get(`/api/users/${session.user?._id}`,{
                        params: {
                            API_ROUTE_SECRET: process.env.LOCAL_API_KEY
                        }
                    })
                    console.log(fetchUserInfo) //  Output: Code 401
                    delete fetchUserInfo.data.user.password 
                    delete fetchUserInfo.data.user.admin
                    fetchUserInfo.data.user && localStorage.setItem('userSession', JSON.stringify(fetchUserInfo.data.user))
                }catch(err){ 
                    console.log(err)
                }
            }
            checkUserInfo()  
        }else{
            localStorage.removeItem('userSession')
        }
    }, [session])

[id].js

import db from "@/database/connect"
import Users from "@/database/modals/users"

export default async function handler(req, res){
    const {id, API_ROUTE_SECRET} = req.query
    console.log('key', API_ROUTE_SECRET) // Output: undefiend
    if(API_ROUTE_SECRET !== process.env.LOCAL_API_KEY){
        res.status(401).json({error: 'Unauthorized User..'})
    }

    if(req.method === 'GET'){
        try{
            await db.connect()
            const userInfo = await Users.findById(id)
            await db.disconnect()
            if(userInfo){
                res.status(201).json({user: userInfo})
            }else{
                res.status(404).json({error: 'User not found'})
            }   
        }catch(err){
            res.status(404).json({error: 'No Data For This User'})
        }
    }else{
        res.status(500).json({error: 'ONLY GET REQUESTS ARE ALLOWED'})
    }
}
