I'm having a lot of difficulty setting up Kontakt in my FL Studio

Zor

I don't have a midi keyboard so I use my keyboard, and I've been trying to search for help with the problem of sound not coming out but the UI that people use to instruct(for example, "click this certain symbol next to that symbol") is different from mine

And when I tried to use the midi keyboard in the plugin itself, it doesn't react to me pressing my laptop keyboard keys, and even if I press the keys manually there's no sound, I checked and I can't find

What happens in Kontakt in standalone? Can you play the notes on the onscreen keyboard?
