Ps4 controller to connect to Huawei P20?

I wanted to connect my ps4 controller to my phone and try to play fortnite. Although I can connect ps4 controller, but he is not shown me in the app "Octopus" and on the phone is no reaction from the controller (so if I press any key nothing happens on the phone). Am I doing something wrong or do I need any app? It seems to me somehow, as it would not work on the P20 at all.

No, that is not possible! But only if you had previously smoked 3 heads of grape mint and watched a video of MGP, Klengan and Manultzen. Then that works:-)
