Inject script into Worker

Hello, I have the following javascript class

class MinhaClasse {
    static list() {
        return fetch('/api/endPoint', {
            method: 'GET', 
            headers: {
                'Authorization': Auth.getBasic()
            }
        })
    } 
}

When inside the web worker I call MinhaClasse it is undefined! how can I inject it into the worker?
