Magisk – New systemless root option built by xda developers. To manage root permission, you need to flash the magisk module (zip) file and install the magisk Manager app on your phone. Links to both the files are below.

In case you’d like to install supersu to manage root permissions, here is the link.
Note: If you use UPI apps like Tez/PhonePe you won’t be able to use them after installing supersu, use magisk and enable hide magisk for “such UPI apps” from the magisk Manager app.
