        Sample output:
         
        ServiceGroupName : ERWebServices
        ServiceName : ERPullSolutionFromRepositoryService
        OperationName : Execute
        Parameters : {@{Name=_request; Type=PullSolutionFromRepositoryRequest}}
        Return : @{Name=return; Type=PullSolutionFromRepositoryResponse}
         
    .EXAMPLE
        PS C:\> Get-D365RestServiceGroup -Name "ERWebServices" | Get-D365RestService | Get-D365RestServiceOperation | Get-D365RestServiceOperationDetails

    .LINK
        Add-D365ODataConfig
         
    .LINK
        Get-D365ActiveODataConfig
         
    .LINK
        Set-D365ActiveODataConfig
         
    .NOTES
        The OData standard is using the $ (dollar sign) for many functions and features, which in PowerShell is normally used for variables.
         
        Whenever you want to use the different query options, you need to take the $ sign and single quotes into consideration.
         
        Example of an execution where I want the top 1 result only, from a specific legal entity / company.
        This example is using single quotes, to help PowerShell not trying to convert the $ into a variable.
        Because the OData standard is using single quotes as text qualifiers, we need to escape them with multiple single quotes.
