The following added to the template would return a string comma-separated list of the top event names.

Dear Mr. Richard Swierk,

Thank you for your support.

Could you please clarify where exactly I should place the command, and which macro should be used with it?
Should I use:

• macro get_note(note, get_children=True)

• macro get_row(label, field_name)

• or macro get_artifact(art)?

Your guidance is highly appreciated.

Best regards,

None of those macros should be used.

The command {% set topEventNames = template_helper.get_datatable_value_array(template_helper.get_incident_value(incident, 'id'), 'qr_offense_top_events', 'event_name') %} will create a variable named topEventNames that's value will be a list of all the top event names from the data table qr_offense_top_events. You can then take that list and format it how you want in the email template.
