Authorization failed on a fetch request to the Brawl Stars API - ajax

Question

I'm trying to send a get request with fetch API to ask the brawl stars API server. I've created an API KEY associated with my IP address. I've tried everything, but I got a 403 response from the server.
Here is my code :
const url = 'https://api.brawlstars.com/v1/players/...';
const token = '...';
const headers = new Headers({
'Accept': 'application/json',
'Authorization': 'Bearer ' + token
});
const options = {
method: 'GET',
headers: headers,
mode: 'cors',
cache: 'default'
};
fetch(url, options)
.then(response => response.json())
.then(console.log)
.catch(console.error);
In the console there is the message : No 'Access-Control-Allow-Origin' header is present on the requested resource because of cors policy.
When I test the request on Insomnia, it works well !

I had a problem with the Brawlstars API a little while back when I was making a Brawlstars command for my Discord bot. I was able to get the API to work however with the following code.
const playerurl = 'https://api.brawlstars.com/v1/players/';
const getJSON = async url => {
try {
const response = await fetch(url, {
method: 'GET',
headers: {
Accept: 'application/json',
Authorization: 'Bearer <yourapitoken>',
},
});
if(!response.ok) {throw new Error(response.statusText);}
const data = await response.json();
return data;
}
catch(error) {
return error;
}
};
getJSON(playerurl).then(data => {
console.log(data);
}).catch(error => {
console.error(error);
});
I hope this works for you!
