As you can see [here](LauncherApps  |  Android Developers, all app icons will be visible.

As of Android Q, at least one of the
app’s activities or synthesized
activities appears in the returned
list unless the app satisfies at least
one of the following conditions:

The app is a system app.

The app doesn’t request any permissions.

The app doesn’t have a launcher activity that is enabled by
default. A launcher activity has an
intent containing the ACTION_MAIN
action and the CATEGORY_LAUNCHER
category.

Additionally, the system hides synthesized activities for some or all apps in the following enterprise-related cases:

If the device is a fully managed device, no synthesized activities for any app appear in the returned list.

If the current user has a work profile, no synthesized activities for the user’s work apps appear in the returned list.
