PowerApps not pulling Employee Phone number from SharePoint List

I have created Employee Directory PowerApps, data connection I am using is SharePoint list. In SharePoint list pulling data for Phone number field from Active Directory. I have added Employee Name, Employee Photo, Employee Department and Employee Phone number label in PowerApps, under gallery control. SharePoint list connection showing information in PowerApps, except Phone number. I am using formula (Thisitem.Name.Phone). Phone number field is people and group field in List.

This formula is working fine for email (Thisitem.Name.email). Note:email field is same as Phone field. But not working for phone number. Please let me know how to pull phone number from SharePoint list and show it is PowerApps?

Thank you in advance.
