Automapper mapping to properties from a nested object

i have an issue with mapping from source a class that has properties which are in a nested object of a parent class to be mapped to destination a class which have no nested objects.

This is my destination class

 public class SCS_OUT_Manifest 
    {
      
        public string ShipperAddress1 { get; set; }
        public string ShipperAddress2 { get; set; }
        public string ShipperAddress3 { get; set; }
       
    }

This is my Source class

public class CreateManifestFromToDto
    {
        public CreateManifestShipperDetailsDto From { get; set; }
    }
    
      public class CreateManifestShipperDetailsDto
    {

        public string ShipperAddress1 { get; set; }
        public string ShipperAddress2 { get; set; }
        public string ShipperAddress3 { get; set; }
    }

I tried something like below, but does not work.

 CreateMap<CreateManifestFromToDto, SCS_OUT_Manifest>()
                .ForMember(dest => dest, src => src.MapFrom(s => s.From));
