Need: Tasker/Zooper Widget to close all recent apps.

I cannot figure out how to close all Recent Apps automatically.

Hardware: Note 4

Android: 5.5.1

Launcher: Next 3D

To close the recent apps manually I hit the lower right button on my phone and then the lower left button.

I would like a button that does both and perhaps closes them automatically at say 11:30 PM.

I have been experimenting with Tasker and Zooper but I cannot figure it out.

The Next Launcher leaves all recent applications open for quick access. They just sit there and take up memory/power.

Thanks, CraigM
