[QUESTION] My currency is not changing to AUD. Please help.

I tried every solutions here but fix at all. Please have a look at my code and let me know how to change the currency to AUD.
things I have tried: -> Adding &currency=AUD at the end of the script -> Adding options={{ currency: 'AUD' }} in PaypalButton tag. -> Adding currency= 'AUD' in PaypalButton tag.
my OrderScreen code:
import React, { useState, useEffect } from 'react'
import axios from 'axios'
import { PayPalButton } from 'react-paypal-button-v2'
import { Link } from 'react-router-dom'
import { Row, Col, ListGroup, Image, Card, Button } from 'react-bootstrap'
import { useDispatch, useSelector } from 'react-redux'
import Message from '../components/Message'
import Loader from '../components/Loader'
import {
  getOrderDetails,
  payOrder,
  deliverOrder,
} from '../actions/orderActions'
import {
  ORDER_PAY_RESET,
  ORDER_DELIVER_RESET,
} from '../constants/orderConstants'

const OrderScreen = ({ match, history }) => {
  const orderId = match.params.id

  const [sdkReady, setSdkReady] = useState(false)

  const dispatch = useDispatch()

  const orderDetails = useSelector((state) => state.orderDetails)
  const { order, loading, error } = orderDetails

  const orderPay = useSelector((state) => state.orderPay)
  const { loading: loadingPay, success: successPay } = orderPay

  const orderDeliver = useSelector((state) => state.orderDeliver)
  const { loading: loadingDeliver, success: successDeliver } = orderDeliver

  const userLogin = useSelector((state) => state.userLogin)
  const { userInfo } = userLogin

  if (!loading) {
    //   Calculate prices
    const addDecimals = (num) => {
      return (Math.round(num * 100) / 100).toFixed(2)
    }

    order.itemsPrice = addDecimals(
      order.orderItems.reduce((acc, item) => acc + item.price * item.qty, 0)
    )
  }

  useEffect(() => {
    if (!userInfo) {
      history.push('/login')
    }

    const addPayPalScript = async () => {
      const { data: clientId } = await axios.get('/api/config/paypal')
      //const curren = 'AUD'
      const script = document.createElement('script')
      script.type = 'text/javascript'
      script.src = `https://www.paypal.com/sdk/js?client-id=${clientId}`
      script.async = true
      script.onload = () => {
        setSdkReady(true)
      }
      document.body.appendChild(script)
    }

    if (!order || successPay || successDeliver || order._id !== orderId) {
      dispatch({ type: ORDER_PAY_RESET })
      dispatch({ type: ORDER_DELIVER_RESET })
      dispatch(getOrderDetails(orderId))
    } else if (!order.isPaid) {
      if (!window.paypal) {
        addPayPalScript()
      } else {
        setSdkReady(true)
      }
    }
  }, [dispatch, orderId, successPay, successDeliver, order])

  const successPaymentHandler = (paymentResult) => {
    console.log(paymentResult)
    dispatch(payOrder(orderId, paymentResult))
  }

  const deliverHandler = () => {
    dispatch(deliverOrder(order))
  }

  return loading ? (
    <Loader />
  ) : error ? (
