Add properties to ApplicationUser

[JonathanUzcateguiG]

Good afternoon. I am trying to extend the ApplicationUser class by adding first name and last name, and then apply the migration to see the changes in the database. So far, I haven't been able to, and I've encountered various problems. Do you have any suggestions? I don't know if I'm doing something wrong.

public class ApplicationUser : IdentityUser
{
string? Name { get; set; }
string? LstName { get; set; }

}

dotnet ef migrations add AddFirstNameAndLastNameToApplicationUser --context ApplicationDbContext --project Infrastructure.csproj
but it doesn't work (does not create the migration.), and I wanted to know how to make the login return these created data: first name and last name.

Thank you for the help you can provide
