This is not true. An app _was_ actually installed on my device. The device isn't rooted, but I have Developer Options enabled and I can see that the folder /data/data/gov.ma.covid19.exposurenotifications.v3 exists.
Logcat also shows that this isn't a Google Play misconfiguration where it would show details about an application as if it were installed. Executable code was installed and run on my phone.
