Power Apps - replace position of First name and Last name in User().DisplayName

Question

My problem is that my Azure Active Directory show DisplayName attribute as First name + Last name.

My goal in Power Apps in Label text, show User().DisplayName as Last name + First name.

If i use Concatenante and Split formula:

Concatenate(Last(Split(User().DisplayName, " ")), ", ", First(Split(User().DisplayName, " ")))

I got this error:

Invalid argument type (Record). Expecting Text value instead.

Thank you for any advice

Last(Split(User().FullName, " ")).Value & " " & First(Split(User().FullName, " ")).Value
