Screen Lock Service as a Device Administrator

Background: >I was looking at the device administrators of my phone in the settings and saw a device administrator called "screen lock service". It's description is "Activating this administrator will allow the app Google play services to perform the following operations: set password rules". A previously unsettled question is found [here](https://android.stackexchange.com/q/229222/332973) . I searched the net for the apk file of the application but could not find one. So as per suggestions, I ran adb shell dumpsys package resolvers | sed -n /android.app.action.DEVICE_ADMIN_ENABLED/,/:/p The output for the above code was: android.app.action.DEVICE_ADMIN_ENABLED: 438a74 com.motorola.demo/.admin.DemoModeAdminReceiver 2acd3de com.google.android.gms/.auth.managed.admin.DeviceAdminReceiver 36b5d24 ch.deletescape.lawnchair.ci/ch.deletescape.lawnchair.gestures.handlers.SleepMethodDeviceAdmin$SleepDeviceAdmin 42aae3e com.google.android.gms/.tapandpay.admin.TpDeviceAdminReceiver 8efd08d com.google.android.gms/.kids.account.receiver.ProfileOwnerReceiver 9b4f242 com.google.android.gms/.mdm.receivers.MdmDeviceAdminReceiver a9980b6 com.oasisfeng.greenify/.DeviceAdmin b5771b7 com.google.android.gm/com.android.email.SecurityPolicy$PolicyAdmin com.motorola.internal.intent.action.INETCONDITION_REPORT: The data for the code is quite unsettling for the fact that none seem to correspond to *screen lock service*. \ For reference, I am using Moto G5 Plus (not rooted, stock build with no customizations) Also note that, I own another **same** device which is rooted and runs Pixel-Experience (Android 10 latest build) and unfortunately it does not have the *Screen Lock Service*. An insight/breakdown for this application is helpful.
