swipe up gesture

I want to integrate my own app drawer into my theme and make it visible through an swipe up. How can I do that? (I use the Nova launcher)

You can add a second page to your preset and then, you can put your app drawer in the second page and use an scroll animation with a 90 angle and 130 to 140 speed, this are going to scroll vertical, use normal scroll background animation(no vertical scroll)

Then in Nova go to the gestures and set swipe up to go to the second page and swipe down to go to the first page.

Thank you!
