AuthKit UI service appeared in my Screen Time report on iPhone

what is authkitUIservice? I was looking through my screen time and it said this was one of my most used apps. i used reddit today and then deleted it later as i didn't enjoy it. I wondered if this could be it but then when i googled it to find an answer there were suggestions of it being a sign that my phone has been hacked. Please answer I am quite worried
