How to bypass final confirmation dialog?

I created a cron job to auto renew the cert.

But it always prompts the finial confirmation blue window, says " Your existing certificate has been successfully renewed, and the new certificate has been installed. You should test your configuration at: www.ssllabs.com/xxxxx". And stop proceeding the following commands.
How can I bypass this dialog? Looked the letsencrypt-auto --help all, but not found the switch to turn this off. I do not want to use webroot plugin and config file.
Thanks for the help.

See Letsencrpyt-auto requires manual interaction on renewal

I think the solution is that you need to add certonly when renewing

@monthly ./letsencrypt/letsencrypt-auto certonly --renew-by-default --server https://acme-v01.api.letsencrypt.org/directory --no-redirect -d example.com -d www.example.com && service apache2 reload

Thanks for the reply.
This command still needs to choose 'how would like to authenticate with the Let's enrypt Ca?, Apache or standalone'.
So the working command for me is,

@monthly ./letsencrypt/letsencrypt-auto certonly
--renew-by-default --server
https://acme-v01.api.letsencrypt.org/directory --no-redirect --apache -d
example.com -d www.example.com && service apache2 reload
