Hi , 
I am using smtp for email sending and need to override both the getContent as well sendEmail method , getContent to change the subject and sendEmail method in order to check whether email has been send successfully.
ThirdPartyPasswordless.init({
      emailDelivery:{
        service: new SMTPService({
          smtpSettings,
          override: (originalImplementation) => {
            return {
                ...originalImplementation,
                getContent: async function (input) {                               
                    let originalContent = await originalImplementation.getContent(input)
                    originalContent.subject = EMAIL_SUBJECT;
                    return originalContent;
                },
                sendEmail: async function (input:any){
                  console.log(1)
                  await originalImplementation.sendEmail(input)
console.log('mail sent successfully')
                }
            }
        }
        })
      },

but in sendEmail await originalImplementation.sendEmail(input) is giving error in sendEmail function.
I want to use AWS SES smtp service and they are asking how u are handling the email bounces and complaints. how can we handle this part.
