Microsoft Graph: Problem getting user authorization_code

Question

I'm having a problem to get the Authorization code of the user.

After the login, I get the user code in URL and after that I go get the access_token with Ajax, But when I do that, I am getting an error :

AADSTS90023: Cross-origin token redemption is permitted only for the 'Single-Page Application'

Here my code :

const url = window.location.href;
    const code = url.slice((url.indexOf("=")+1), url.indexOf("&"));
    console.log(code)
    let form = new FormData();
    form.append("client_id", "48701536-c150-48f2-917b-730d855f316b");
    form.append("client_secret", "RzZ7Q~-GEYd6WayuMKmVXvH2w.Q7GjuaoHNEy");
    form.append("scope", "https://graph.microsoft.com/user.read");
    form.append("redirect_uri", "http://localhost:3000/Pagina1.html");
    form.append("grant_type", "authorization_code");
    form.append("code", `${code}`);
    // Tried with, but no effect ->  https://cors-anywhere.herokuapp.com/
    $.ajax({
        url: "https://login.microsoftonline.com/consumers/oauth2/v2.0/token",
        method: 'POST',
        "timeout": 0,
        crossDomain: true,
        async: false,
        processData: false,
        mimeType: "multipart/form-data",
        contentType: false,
        data: form,
        success(response) {
            console.log(response)
        }, error(response){
            console.log(response)
        }
    })
