I went to the app registration of that service principal and there I went to certificates & secrets I see it has not created new secret.
Well, actually the command New-AzADSpCredential did create a new secret for you.
Firstly, you need to know the relationship between App Registration(AD App) and Service principal, see Application and service principal objects in Azure Active Directory.
In short, the service principal is the local representation for the AD App in a specific tenant. When you create the secret for the service principal, it will not appear in the Certificates & secrets blade, you can just get it with Get-AzADSpCredential.
If you want to reset the secret that you can find in the portal, you need to reset the sceret for the AD App(i.e. App Registration) via Remove-AzADAppCredential and New-AzADAppCredential.
You could refer to the sample below, it resets a secret with value ce96a0ed-5ae8-4a5a-9b3c-630da9ea3023, it is valid for one year, you can find it in the portal.
$obj = (Get-AzADApplication -DisplayName joyappv2).ObjectId
Remove-AzADAppCredential -ObjectId $obj -Force
$azurePassword = ConvertTo-SecureString "ce96a0ed-5ae8-4a5a-9b3c-630da9ea3023" -AsPlainText -Force
$date = Get-Date
$newCredential = New-AzADAppCredential -ObjectId $obj -Password $azurePassword -StartDate $date -EndDate $date.AddYears(1)
Note: You could not get the secret value again after creating it, so please store it when creating.
