No need to use previous version, i hacked everything in the game using current version.
First thing you need to do is to make a dump.cs of the game( with metadata and libil2cpp.so) in the Il2CppDumperGUI app.
Now Iam giving a script named field_offset_finder use this script with the help of dump.cs
Open dump.cs search what you want to hack. Copy the Class Name and field or offset of that thing now goto to gg open script paste class name and field or offset( check if you are using 32bit game if 32bit then click try 32bit) and run the script it will give you result change it as you want.
For Example if you want to hack chest card, open gg exicute script put ManagerCardsGenerator in Class Name and 0×8 , 0×10 (for minimum cards, search both one by one using same class name given) run script some results will be shown edit all to 998, for max cards put 0×C and 0×10 one by one using same class name given , now edit all these to 999 , you are done all chest will give you 998 to 999 manager cards per open.(i found these class name and offset using dump.cs)
You can also change chest rewards, for this put RewardType in class name and 0×8 in field , all rewards id will be shown by running script (if you don't know about rewards id search it dump.cs)
