Should allow u to do hardware spoofing then just do mic and camera usb passthrough.
If u want to cheat u can probably take a page out of the valorant cheaters handbook and use image2text screencapture so u can copy out of the vm and maybe a usb emulation flashed onto a rasberry pi to type out a paste (hell a autohotkey to intercept ctr+v and type out ur clipboard and ctr+c to copy selextdd text might also work). Can also probably do whats called gohsting by modifying virtualbox guest addons configs and compiling so the vm detection doesnt recognise it as a vm driver. Actually it might honestly just work with the guest addon loaded in memory and then deleted from disk then make a snapahot of this state u can roleback to as needed.
Most of these proctoring solutions and shittilly implemented and steal code from viruses i found one the other day that just recompiled an opensource rat but left out half of it.
Also if u could provide me a download link for said software id love to decompile it.
