go to memory pages and hit the bulky arrow
Don't put in an address instead just hit XA and select the libil2cpp.so file (there isn't one for this game so I don't circle anything but your menu will look something like this choose the one with the libs file path)
This should give you the start of the lib files address, long press this and hit "offset calculator" then type in the offset from Dnspy and put a lowercase h and hit "go to"
This should bring you to the correct address
Shout out to @NoFear (sorry for pinging you) for his reply to my thread when I was wondering about searching offsets months back
Pretty sure from there you can search the address once you know it in hex which should help you go about automating the process with a script
