Asset Bundle Extractor cannot change audio .npk files?

[EarySummer7]

Hello, in the Korean DNFM game, the .npk file with audio cannot be edited by the plug-in button in the software. That is, the audio .npk file "Plugins" does not have an "Edit" button, only "Export audio". So do you think there is any way to replace the ogg audio file in the .npk file? I would like to change the background music of the game, thank you.
您好，在韩国的DNFM游戏中，打开带有音频的.npk的文件不能被软件中的插件按钮编辑，也就是音频.npk文件“Plugins”没有"Edit"按钮，只有“Export audio”。所以您看有什么办法更换.npk文件中的ogg音频文件吗？我想换个游戏背景音乐，谢谢。
