Decoding/decrypting a TextAsset (.bytes file) from a Unity android game

[Paselfa2]

Hi,
I try to decrypt / decoding the TextAssets (.bytes file) of the android game Slime Isekai Memories (from Bandai Namco). I got the TextAssets by using AssetStudio. I already tried out to find the function in the apk but I don't have to much experience with app programming (my best guess I had was it is in com -> unity3d.player) but maybe it is somewhere else. It was possible, see here https://github.com/Coded-Bots/SLIME-...ionUnlock.json

Here are some example TextAssets (.bytes file):

Thanks in advance!
