Search nested field with filtering

Hello,
I need help in searching "BirthDate" field and in response I only need the results of BirthDates(source filtering).
Can anyone help ?

Sample document:

{
  "Payload": {
  
         "ProfileInfo": {
      
                 "Profile": {
        
                      "Customer": {
                             "detail1": {
                                    "Gender": "Male",
                                    "BirthDate": "1990-01-28"
                                      },
									  
							  "detail2" : {
							         "Name":"abc",
									 "ID":123
									   }
        }
      }
    }
  }
 }
