I want to automatically add a header to every request in my whole collection using this pre-request script:

pm.sendRequest({
    url: "https://mydomain/ers/config/endpoint",
    method: 'GET',
    header: {
        'content-type': 'application/json',
        'accept': 'application/json',
        //'x-site-code': pm.environment.get("x-site-code")
        'X-CSRF-TOKEN': 'fetch'
    },
    body: {
        mode: 'raw'//,
        raw: JSON.stringify({ email: pm.environment.get("email"), password: pm.environment.get("password") })
    }
}, function (err, res) {

    pm.environment.set("X-CSRF-TOKEN", "Bearer " + res.json().token);
});
