Anyone use Manjaro (Linux)

[Mr_Robot]

I wouldn't call myself a Linux pro,more like an upper novice. I'm familiar with Debian and was able to install things with very little trouble. I am having trouble installing two apps called Ulauncher and Stacer. The instructions for both are not working for me. I would love help some help if you can. Thanks

UPDATE
I got it figured out,it was on flatpack. I didn't know it gave you options to search different repositories in its own store.
