FluentSMTP using AWS SES V1 or V2?

Shahjahan Jewel, is FluentSMTP using AWS SES v1 API or v2 API? From what I'm seeing, it looks like it is using v1 which has a limit of 10MB per message. Is there a way to make it use v2 which has a 40MB limit per message?

Edit to add: I switched to using SES via SMTP which supports the 40MB limit but I'd prefer to use the API instead if that is possible.

Thanks.
