Understanding the function of .so files in an APP

An app uses .so files, but these are not integrated into the Android APK. They are downloaded after installing the app and after registration and are also updated regularly.

There are different folders in the downloaded data, each of which always contains a .so file and a different number of files (e.g. 11) that have the extension .0000. Perhaps they are related to the shared-object files.

For the sake of interest, I would like to know what is in the files.

Previous attempts: Android-Studio only shows unreadable characters, Editor as well.

JADX shows me the binary code, which unfortunately doesn’t really help me either.

Now my question is, what possibility is there to open these files and display them readably?
