Has anyone been able to use the UpdateSingleSalesforceObject function on an Account/Contact in Person Accounts (specifically Contact fields such as Email, FirstName, LastName)? I'm able to retrieve the contact using RetrieveSalesforceObjects but I obviously can't write to Contacts as it is read-only on Person Accounts.
I've tried replacing "Email" below with "Account.PersonEmail", "PersonEmail", "Email__pc". None of the above works.
set @result = UpdateSingleSalesforceObject('Account','0031U00000KE9UTQA1','Email','firstname.lastname@example.org')
