To create an optional argument in a library or activity

Hi all,
I’m creating a customised library,
I have a string argument named in_Arg.

I’m passing this argument ( in_Arg) to a type into activity.
I want to have this argument optional, i.e. if value is given for this argument then the same value must be entered otherwise the value must be skipped.

Any idea?

Thanks in advance

have a check on the library implementation for following:

  • react on the passed / non passed argument within the flow
  • checking the argument was not passed:
    isNothing(in_Arg) OrElse String.IsNullOrWhitespace(in_Arg)
