Import-Module icinga-powershell-framework fails in ContranedLanguage powershell when Applocker is enabled

I am trying to setup the Icinga for Windows with the PowerShell Framework on an Domain managed system.
Do to policy reason the Icinga agent has to run as an domain user and I have configured icinga agent like that (following the instruction.

When I run an powershell as that icinga service user to debug some stuff and try to import the icinga-powershell-framework module I get an error

Import-Module : This module uses the dot-source operator while exporting functions using wildcard characters, and this
is disallowed when the system is under application verification enforcement.

I guess this is caused due to the fact that AppLocker is active on the system and the user is not an Adminstrator and gets an PowerShell with ContrainedLanguage LanguageMode

Expected Behavior

I would like to be able to do an Import-Module icinga-powershell-framework as an normal user even when AppLocker is enabled.

Current Behavior

Failure to do an Import-Module icinga-powershell-framework

Possible Solution

Steps to Reproduce (for bugs)

1. System with AppLocker enabled somehow (details are beyond my capabilities
2. Run PowerShell as normal user.
3. Verify LanguageMode is ConstrainedLanguage by displaying $ExecutionContext.SessionState.LanguageMode
4. Try to do an Import-Module icinga-powershell-framework

Context

I am trying to setup Icinga agent on an system where I will manage it but won't have Administrator access but can run stuff as the icinga service user
