The first has incorrect use of the definite article (the users, the features), but to be honest it’s less about specific grammar syntax/rules and more about making writing easier to understand and more concise.

Second is preferred.

When you say “need the features”, that immediately makes me think “which features?” because it reads as if you are referring to some previously mentioned features.

No offence but I couldn’t understand the example without the correction.

Yes, but only one is easy to read correctly.

The 'features' in the sentence are indefinite - they're not fully specified - so clearly adding a definite article isn't right.
