Looking for Spoofer where I can completely be AFK

So basically I bought a broken a40 on a flea market and fixed it and now im looking for a spoofer that basically plays the game while im at work. I searched a little while and found someone posting on facebook marketplace that he sells a rooted phone with linage os and a spoofer that basically fills my description. Any idea what the name is? While im at it, surely a rooted android is the safest way to spoof right? Thanks in advance
