Use OAuth2 with Omnis 10.1?

In your gmail settings there is a setting that essentially says “Allow less secure apps to access your account”.. I had to set this in order to send email with Omnis through Gmail.. I’m not using Oauth, though, I am just using SMTPSend.. but I think the same thing would apply.. find this setting and set it and see if you get success.

I thought I had to update to using Studio 10.2 which has added an OAuth2 worker object to the OW3 set of Worker objects.  But then looking in the docs I find in Chapter 7 under Web Worker Objects (OWEB) a section on "SMTP Client Workers" which mentions it can work with OAuth2.  However, I believe this relies on Java?  So I would need to have Java installed to use this?
