'Clear Android APP's cache with command line

I'm trying to clear an app's cache using shell command, but I failed to completely clear it.

My understanding is that an app's cache are in the following folders:

    /data/data/<app package name>/cache
    /data/data/<app package name>/code_cache
    /data/user_de/<user id>/<app package name>/cache
    /data/user_de/<user id>/<app package name>/code_cache

So, I have issued "rm -rf {paths above}/*" one by one for these 4 folders. However, while the cache size is decreased as seen in android's native "App Info", it is not zero. I can only completely clear it by pressing "Clear Cache" in there.

I'm puzzled where else the extra cache locations could be? I checked there are files in /storage/emulated/0/Android/data// , but even "Clear Cache" does not remove these files.

Any ideas where are the other cache locations of an app?
