helmet.hidePoweredBy() is not working

Hello everyone,

basically, I started taking this Information Security course and I passed the first step(installation etc…) after that I had to remove a header with the middleware helmet.hidePoweredBy() so I tried with version 3.21.3 and it didn’t work so I downgraded the version to 2.3.0 and tried again… After multiple attempts of it not registering as a correct answer I lost hope so here I am.
