How to properly connect a script from helmet to node?

Question

Node.js

Refused to load the script ' https://code.jivosite.com/widget/qBBQfaHsH1 ' because it violates the following Content Security Policy directive: "script-src-elem 'self' https://cdnjs.cloudflare.com/ajax /libs/materialize... 'unsafe-inline'".
After connecting the helmet, you have to make additional settings in the Content Security Policy directive. I do it like this (below is the working code):

app.use( helmet({
      contentSecurityPolicy: {
         directives: {
            ...helmet.contentSecurityPolicy.getDefaultDirectives(),
            "img-src": ["'self'", "https:"],//это для загрузки картинки http, без этого не работает
            "script-src-elem": ["'self'", "https://cdnjs.cloudflare.com/ajax/libs/materialize/1.0.0/js/materialize.min.js", "'unsafe-inline'" ] 
         }, // это для подключения внешнего скрипта , без этого не работает
      },
     })
)
