jquery ajax header sending error Access to XMLHttpRequest at https://discord.com/api/guilds/1234567890

<script>
    const URL = "https://discord.com/api/guilds/899175503565553714";
    $.ajax({
        url: URL,
        type: "GET",
        headers: { Authorization: 'Bot ' + token } })
</script>

Here is my code

index.html:1 Access to XMLHttpRequest at 'https://discord.com/api/guilds/899175503565553714' from origin 'null' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource.

How can I send headers and receive values ​​successfully with jquery ?
