Im trying to set a custom cookie, for axios requests. But it's not working.

Thats my code

const axios = require('axios');
axios.defaults.withCredentials = true;

const client = axios.create({
    withCredentials: true
});

let url = 'https://google.de';

client
    .get(url, {
        headers: {
            Cookie: [
                'cookie1=value;'
            ],
            'Access-Control-Allow-Origin': '*',
            'Access-Control-Allow-Credentials': true,
            'Access-Control-Allow-Headers': 'Origin, X-Requested-With, Content-Type, Accept',
        }
    })
    .then(res => {
        console.log(res.headers['set-cookie']); // Im getting "undefined"
    })
    .catch(err => console.error(err));

i tried different ways, but have no luck. maybee any one know how i can set custom cookies in axios? or recommend a better library to do that..
