Conversion of string containing "AM" or "PM" to datetime

Given the string

str = "4/21/2022 8:48:40 AM"

I want to convert it to a datetime

datetime

21-Apr-2022 08:48:40

However, using

d = datetime(str, "InputFormat", "MM/dd/yyyy HH:mm:SS")

gives an error, while

d = datetime(str, "InputFormat", "MM/dd/yyyy HH:mm:SS a")

gives

datetime

21-Apr-2022 00:48:00

what is not what I want or even expect (hours and seconds both set to zero).

str = "4/21/2022 8:48:40 AM";
dtm = datetime(str, "InputFormat", "M/d/u h:m:s a")

dtm = datetime
   21-Apr-2022 08:48:40
