Sending email

From Google extension I made a new conference using google calendar, I expect that also an email will be send but this doesn’t happen so, if the other guy are not using calendar they are not able to connect.
In the test i sent the email but I expect will be done automatically.

The situation is a bit different.
The mail was sent but there is not in my sent mail (Gmail) so when I need to start the webconference I can only do from Calendar and not from Gmail.
Could be useful to have also the mail in my sent mail.
