I wouldn’t go that far. It involves the command line, yes, but it is doable and has been done by many non-really-well-versed-IT-people 
.
Note that even though it’s from their forum, this is not /e/OS-specific, this is the standard way provided by Android to do this.
I think not every Android OS provides the package name in the settings like /e/OS does, though, but there are other ways to know it like the Google Play Store URL of an App (https://play.google.com/store/apps/details?id=com.google.android.gm → package name com.google.android.gm), “bloatware” lists in the internet or App/package manager Apps.
