Is there a hide app feature on P20?

This feature has been removed since EMUI 5.1. It used to be able to pinch apart a home screen to get to the hide apps screen.

Yes, the feature has been removed from EMUI. The workaround are the followings:

1. Go to the device’s Settings > Security & Privacy > PrivateSpace. Following the on screen instructions to setup the private space. Then, install the apps you want to hide from public eyes in this space.
2. Or, go to device’s Settings > Users & accounts > Users > Add guest, and follow the on-screen to setup a Guest account. Then, install the apps you want to hide in the Guest space.

But they are allready installed on the phone, and I want them gone from the homescreen
