Is it possible to send a file attachment using the gmail integration?

As above, is it possible to send a file attachment using the gmail integration, and if so could someone please provide me with a simple example of how to do so.

Yes, read my response to your original question about IMAP, that link I gave you explains how you can attach a file.

I’m looking for something that’s specific to the gmail integration, rather than using smtp to send a message through gmail.
