unable to list the properties of azure ad user (createddatetime)

I have many users in my Azure AD tenant, I want to collect the data of the users when they are created.

I am able to get the user details by running Get-AzureADUser. So, I just modified the command as

Get-AzureADUser | Select-Object, Mail, createdDateTime

But this returned details but the createdDateTime field was empty. After some research I found that createdDateTime is an extension attribute.

I found this command Get-AzureADUserExtension but now my question is I want to get the list of users with their email and the created date time.

Any script to achieve my scenario?

TIA

I tried to reproduce the same in my environment and got the results successfully like below:

To get the createdDateTime of Azure AD Users with email address, I tried the below script:

$result = @()
$AAD_users = Get-AzureADUser -All:$true
foreach ($AAD_User in $AAD_users) {
$info = [PSCustomObject]@{
Email     = $AAD_User.mail
CreationDateTime  = (Get-AzureADUserExtension -ObjectId $AAD_User.ObjectId).Get_Item("createdDateTime")
}
$result+= $info
}
$result

I am able to get the list of users with createdDateTime successfully like below:
