15% of the users said "there are no features that interest me". What should I do?

Hello everyone: Let me first introduce my troubles. I'm currently starting a business and working on an AI - related image project. Recently, we've been conducting an internal test. We recruited 30 users from the R community to use our product for free. To avoid any suspicion of advertising, I won't mention the product name. The functions are roughly as follows.

“Explore Your Art Effects”“Real-time Facial Animation”“Muscle UP Magic”"Change Hair Color""Face Comes Alive"“Get Your Guardian Spirit”“AI Photo Generator”

About five of our users said "there are no features that interest them". I want to take improvement actions immediately. The only trouble is whether I should add features to satisfy these customers or just focus on the 85% of users who like our product. Our team attaches great importance to user feedback. What should I do?
