Aa ok, I put all my assets in .zip.
And now I make button in html and event handler in file config.js (in Twitch CDN).
But it tells me:
Refused to execute inline event handler because it violates the following Content Security Policy directive: "script-src 'self' https://q5df5bsbaqzml2eayvv29hsnn1ldpt.ext-twitch.tv https://extension-files.twitch.tv". Either the 'unsafe-inline' keyword, a hash ('sha256-...'), or a nonce ('nonce-...') is required to enable inline execution.
