Two questions about TwitchExtention

Extensions

What code did you try.

The HelixToken is returned in the onAuthorised callback. So you would extract it from the variable passed to the callback

Here is an example


let helix = {};
window.Twitch.ext.onAuthorized((auth) => {
    helix = {
        'Client-ID': auth.clientId,
        'Authorization': 'Extension ' + auth.helixToken
    }
});

function collectHelix() {
    if (!window.Twitch.ext.viewer.isLinked) {
        return;
    }
    fetch(
        'https://api.twitch.tv/helix/users/?id=' + window.Twitch.ext.viewer.id,
        {
            method: 'GET',
            headers: helix,
        }
    )
    .then(resp => {
        return resp.json();
    })
    .then(resp => {
        var table = document.createElement('table');
        document.getElementById('helix_log').append(table);
        for (var key in resp.data[0]) {
            var tr = document.createElement('tr');
            table.append(tr);
            var td = document.createElement('td');
            td.textContent = key;
            tr.append(td);
            var td = document.createElement('td');
            td.textContent = resp.data[0][key];
            tr.append(td);
        }
    })
    .catch(err => {
        console.log(err);
    });
}

Not 100% sure what you are intending.

Sounds like you wish to use AllowListing but EBS enforced rather than the Twitch list
