Lock screen notifications?

I have a Huawei Mate 10 Lite with Android 8.0 and EMUI 8.0

My question is now you can download from Huawei themes and enable this I have done and I still need to ZOCKING Engine a lockscreen apk file so the notifications on the lock screen is displayed but this did not and I uninstalled it and wanted it to me again download only the app installs me this file no longer can you please help me

Such errors can occur if the mobile version had an update. I also have a Huawei but can't help you too much because I have not dealt with such a thing!

OK, thanks anyway
