Wich files do i need in my extension?

Extensions
8

yeah i got the loader in my js file. But only in the panel one. For the Config.html i dont have any js function. There is just text. It looks like this

document.getElementById("prev-page").addEventListener("click", prevPage);
document.getElementById("next-page").addEventListener("click", nextPage);

var token, userID, channelID, clientId, helixToken;
var totalPages, currentPage;

const twitch = window.Twitch.ext;

twitch.onAuthorized((auth) => {
    token = auth.token;  
    userId = auth.userId; 
    channelID = auth.channelId;
    clientId = auth.clientId;
    helixToken = auth.helixToken;
});
