SUCCESS-Big Sur 11.5.2 - OPENCORE 0.7.2

Finally got macOS running on my laptop, here are my specs:

CPU: Intel Core i5-8365U

GPU: Intel UHD 620

RAM: 16 GB

Laptop: HP EliteBook 840 G6

Audio Codec : ALC215

WIFI: Intel WIFI6 AX200

I followed dortania's vanilla guide, verything works except camera, microphone(internal and through headphone jack).
Note: I installed macOS on an external SSD and everything is fine (kinda).
