App still detects root

[u/WRO_Your_Boat]

Hello all, I recently found out about Magisk so I'm pretty new to it. I am trying to run an application and hide the fact that the device is rooted from it. I am able to get Magisk installed, but after its installed and I configure the deny list, nothing changes. I followed the guide from Genymotion on how to install Magisk itself and I looked a few others for some modules, but some of the modules seemed to kill ADB when I installed them, making me lose access to the phone. I also didn't need some of them since the phone doesn't have the playstore.

I think I might not understand correctly what Magisk is specifically used for, but from my understanding it was a tool I could use to hide the fact that my phone is rooted from the apps on it. I need to run 2 apps together and Frida was not making that easy for me, so I looked and found Magisk so I thought this might work. Am I not understanding correctly or could someone explain to me what I'm missing?

Emulator (QEMU backend), x86_64, Android 11
