NBitcoin, how to implement wallet restoration? How does it work?

When I make a GET request inside in react, I get blocked by CORS policy error. However if I make the same request inside vanilla js (a simple .js file) I get the appropriate response.

Here is my code in the react:

const axios = require('axios');

function getLatestPrice() {
  const config = {
    url: 'https://api.kraken.com/0/public/Trades?pair=ETHUSDT&since=1656322000',
    method: 'GET'
  };
  
  return axios(config);
}

exports.getLatestPrice = getLatestPrice;

I get the following error:

Access to XMLHttpRequest at 'https://api.kraken.com/0/public/Trades?pair=ETHUSDT&since=1656322000' from origin 'http://localhost:3000' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

My code in vanilla js file

const axios = require('axios');

const url = "https://api.kraken.com/0/public/Trades?pair=ETHUSDT&since=1656322000";


const config = {
  url: url,
  method: "GET"
};

axios(config).then(res => {
  console.log(res.data);
}).catch(err => {
  console.log(err);
});

Here I am getting the correct response.

(I am not controlling the API backend)
