I will try, but my englisch is not so good.
Frist download the necessary files:
ANXCameraUnity_190.BountifulDistantHapuka.zip
ANXFrameworkUnity_190.BountifulDistantHapuka.zip
ANXCameraHotfix.190.BootloopFix.zip
ANX_aux_patch_by_bhatsahab.zip
Install all the files with magdisk wihtout a reboot.
After all files are installed reboot you phone.
Install
ANXCamera Pro from the Play Store.
Run ANXCamera Pro and change this settings:
Portrait Lighting Back = false
Hand Gestures = false
After that you can uninstall ANXCamera Pro.
Open the App-Details from the ANX Camera witch you have installed with magisk.
Go to permissions and give the ANX Camera App all permissions manually (or it will crash at startup).
After that reboot your phone.
If ANX Camera shows only a black screen with buttons, reboot your phone twice.
Edit:
If you have a bootloop, go in the recovery and flash the anx files with your recovery.
