create appointment and forward as ICS attachment

I have a VBA Code that can create an outlook appointment and save it.
it has the basic lines to create a subject, start time, duration, body & ReminderMinutesBeforeStart.
At the end, the code saves the appointment on the calendar.

However, I would also like to be able to immediately forward the appointment as an .ICS file to a different email address.
Please let me know if this is possible.

[Just if you are curious why I need this: Gmail calendar cannot be added to the OUTLOOK desktop program. So, I create appointments in outlook with VBA, and then would like to forward it to gmail, and then add the event to gmail calendar]

Looking forward to your help.
