Manually trigger/resend Fluent Form-specific double opt-in message?

Please consider adding the option to manually trigger/send the form-specific double opt-in email.

I neglected to set up the form properly, and the double opt-in was never triggered. I've corrected the error, and I'd like to ensure that the opt-in message is sent now. However, there is no way I can see to manually trigger the form-specific double opt-in.

I can trigger a generic one from FluentCRM by choosing the contacts and sending an opt-in message, but that capability doesn't exist for the form-specific double opt-in.
