It generates a performance problem with this feature at lighthouse, webpagetest and GTMetrix reports. It is delaying the first paint content at 700ms. The VTEX own app Cookie-script loads a blocking .js, which stops the site from loading until resolved.”

Olá @ViniciusCosta126!

Acredito que já que estamos falando de um tipo de script de consentimento de cookies, ele precisa ser executado de maneira síncrona e antes dos demais scripts.

Tentei buscar na documentação do Cookie Script por recomendações sobre isso e encontrei esse artigo. Infelizmente ele não menciona se o script pode ser carregado assincronamente.

Procurei saber como seria pra outros serviços parecidos e me lembrei do OneTrust. Encontrei essa documentação que não aconselha o carregamento do script de forma assíncrona:

The AutoBlock may not be loaded asynchronously on the page. This means that content rendering is paused until the OtAutoBlock script finishes loading and executing. This is a requirement so that OneTrust can intercept any scripts being added to the page before they load and mark them for consent actioning. If the script were loaded asynchronously, scripts would be able to load without consent.

O que você acha? Uma alternativa que foi recomendado pelo Cookie Script é tentar fazer a integração via GTM, é algo que serve pro seu caso?
