Hi all, I'm building this application that has to send an email to a person who created an item in SPO list.
I have jb007MI6 field in my view form in Power Apps coming from SPO list, however I'm trying to get the persons email so I can send him an email.

Office365Outlook.SendEmailV2('Created By_DataCard1'.DataField, "New onboarding request for " & varRecord.'First Name' & " " & varRecord.'Last Name' & "has been created", "Here is a link to the record <ahref='https://apps.powerapps.com/play/306d698a-804a-4d77-b82a-e7fe447de163?tenantId=8527ffd7-e153-4862-bf90-7a0cab40241e&hidenavbar=true&EmpID=" &varRecord.ID & "'>link</a> here.")
I'm using deep linking function to do so, here is the formula, but i don't know how to get Created By user's email and not display name.
PS: the trick with changing created by filed settings to show email address instead of display name is not working.

I know i can achieve this by story the email address in a separate column, but I'm trying to avoid having extra columns, since by default i have created by person, so i only need to get his email address from O365 directory.

Kiril
