Bliss launcher and it's app switcher

It is off and i dont really use developer settings. Only time i used them was to install the E os and never touched it again. Square button works completly fine i keep activities there is no problem with that. Even during the bug when i cant use my square button activities are kept. After reset of bliss launcher it comes back to working again. I also have a question because when i scrolled throught dev options i saw option of using debuging with root access does that mean my device is already rooted? I said that rooting device is something that scares me but if i would follow the instruction that GnuGorets gave on their’s post would it actually work or does that option just exists even if device isnt rooted? Thank you for your help!
