Identify installed apps android

Question

Trying to get a list of all of the installed apps on the phone. I tried to do this (I took the code from this post and improve it):

PackageManager pm = getPackageManager();
List<ApplicationInfo> apps = pm.getInstalledApplications(0);

List<ApplicationInfo> installedApps = new ArrayList<ApplicationInfo>();

int myFlags = ApplicationInfo.CATEGORY_AUDIO |
        ApplicationInfo.CATEGORY_GAME |
        ApplicationInfo.CATEGORY_IMAGE |
        ApplicationInfo.CATEGORY_MAPS |
        ApplicationInfo.CATEGORY_NEWS |
        ApplicationInfo.CATEGORY_SOCIAL |
        ApplicationInfo.CATEGORY_VIDEO |
        ApplicationInfo.CATEGORY_UNDEFINED |
        ApplicationInfo.CATEGORY_PRODUCTIVITY;

for(ApplicationInfo app : apps) 
{
    if ( (app.flags & myFlags) != 0 && app.icon != 0) {
       installedApps.add(app);    
}

What I'm trying to get is if the app has an icon, which means it appears in the launcher, and if so I add it to my list.

For some reason some apps are missing like "YouTube" and "YT Music" and I don't understand what should I change in order to identify these applications.

Note that google is taking a proactive approach about privacy, It will restrict apps from fetching the device installed apps, unless asking for a specific permission called: QUERY_ALL_PACKAGES

Here's a reference from google official documentation: https://support.google.com/googleplay/android-developer/answer/10158779#zippy=%2Cinvalid-uses%2Cpermitted-uses-of-the-query-all-packages-permission
