Arknights Endfield Closed Beta Wwise *wem extract

[NoNarluire]

Hey everyone, has anyone here worked on the Arknights Endfield audio files? Yesterday I was working on the music from the alpha version of the game and successfully extracted the music (all I had to do was rename the *.chk archives with the audio to *.pck and send those *.pck to AnimeWwiser). Today I was working with files from the Endfield beta, and unfortunately, the method I described above isn't working, and I don't know what to do now. I need to extract normal *.wem/wwise audio from the AKPK, but I don't know how. Please help. If you need the files, here's the link.
