Tried this to no avail:

session.webRequest.onHeadersReceived({
    urls: ['*://*/*'],
}, (details, done) => {
    console.log(details.url, JSON.stringify(details.responseHeaders));
    done({
        cancel: false,
        responseHeaders: details.responseHeaders,
    });
});

Giving this for https://player.twitch.tv/?channel=oyed:
