Failed to install UWP application

I need help with the scenario below

I have a UWP application that is being installed from a service run by the local system user (user SID S-1-5-18) The service executes the following command in powershell:

Add-AppPackage -Path "C:\Dir1\Dir2\Dir3\Windows\App.UWP_2.0.27.0_x64.msixbundle" -DependencyPath "C:\Dir1\Dir2\Dir3\Windows\Dependencies\x64\Microsoft.NET.Native.Framework.2.2.appx", "C:\Dir1\Dir2\Dir3\Windows\Dependencies\x64\Microsoft.NET.Native.Runtime.2.2.appx", "C:\Dir1\Dir2\Dir3\Windows\Dependencies\x64\Microsoft.UI.Xaml.2.4.appx", "C:\Dir1\Dir2\Dir3\Windows\Dependencies\x64\Microsoft.VCLibs.x64.14.00.appx"

However, in this process the error is presented:

The AppX Deployment operation for CodeWith7-CodeWith4-CodeWith4-CodeWith4-CodeWith12_2.0.27.0_neutral_ ~ 3kncj78a7wnxj failed with error 0x80073CF9. The specific error text for this failure is: Add deployment operation rejected in the CodeWith7-CodeWith4-CodeWith4-CodeWith4-CodeWith12_2.0.27.0_neutral ~ _3kncj78a7wnxj package: App.UWP_2.0.27.0_x64.msixbundle installation request because the account of the Local System is not allowed to perform this operation.

I have already done the test and if I change the execution of the service to be performed by a local administrator user the installation is performed. But when run with the local system user it has an error.

I would like to know if anyone knows how to explain to me why I need to be run as an administrator and not by the local system. And if someone chooses to perform in another way to be able to perform the installation with that user.
