Why is my phome doesn't show download on the status bar?

I have a problem that I've been trying to solve for weeks now. My phone doesn't show the download icon on the top left status bar and I don't know what to do. I reset all settings on phone. I didn't mess with the settings at apps. However it has been gone for months now.
I have a Huawei p20 lite phone and it has emui 8.0 android version. Any suggestions what could I do?
