If self-serve recertification training has been enabled (details here), then the link can be sent to the volunteer for them to complete the session.
The link will send the volunteer to a customised page for them. They will have the video to watch and three questions to answer with their reflections.
To complete the training, they need to answer the three questions and press the Submit Answers button
When they press submit, their training will be marked as done, a note will be added to their record with the answers they gave and there will be a notification sent to their CVM.
If training is the final stage of their recertification then they won't be automatically marked as recertified, this still needs to be done manually using the Confirm Recertified button.
