Logging in SW6 with APP_ENV=production

I have question about logging in shopware/symfony.

If I use APP_ENV=production in .env, config-files from config/packages/production will be used like shopware.yaml, framework.yaml and so on.

But with this scenario there is no logging file in var/log as with APP_ENV=dev oder APP_ENV=prod

How can I enable logging?

prod is production.

You should not use APP_ENV=production, use APP_ENV=prod
