Azure Powershell doesn't expand the result when "select-object" is used - azure-powershell

Question

I am quite new to Powershell and I use it only for some Azure work I am recently assigned with.
I noticed a behavior that I can't understand. When I run Get-AzNetworkInterface cmdlet, the field IpConfigurations will displays all details like this
IpConfigurations : [
{
"Name": "ipconfig1",
"Etag": "blabla",
"Id": "blabla",
"PrivateIpAddress": "10.1.2.3",
....
}
]
However, if I append select-object, the result becomes just the {ipconfig}, which is just the name of the field
> Get-AzNetworkInterface | Where-Object { $_.Name -eq "some nic name" } | Select-Object "IpConfigurations"
IpConfigurations
----------------
{ipconfig1}
I have the same result if I view the output with | Out-Gridview. The IpConfigurations field would only show the name. However, it would also show an IpConfigurationsText field that contains all the details. It got truncated so I can't see the full text. By the way, is there a way for the popup GridView window to show the full content? Anyhow, I then tried to select this field in the Shell console but still got nothing.
> Get-AzNetworkInterface | Where-Object { $_.Name -eq "some nic name" } | Select-Object IpConfigurationsText
IpConfigurationsText
--------------------

What is the logic here for the Azure Powershell cmdlet to expand fields here?
Thanks!

You can use the below cmdlet to expand the Ipconfigurations property
Get-AzNetworkInterface | Where-Object { $_.Name -eq "NICName" } |Select-Object -ExpandProperty IpConfigurations
Here is the sample output for reference:
If you want to expand the IpConfigurations Property & project the output in Gridview we would suggest you to use the below PowerShell cmdlet
Get-AzNetworkInterface | Where-Object { $_.Name -eq "NICName" } |Select-Object -ExpandProperty IpConfigurations|Out-GridView -PassThru
