Let's Encrypt certificate is added to server pool when it is issued by clicking on + Let's Encrypt button in Home > Tools & Settings > SSL Certificates page or using command line below:
# plesk bin extension --exec letsencrypt cli.php -d %server_hostname% -d www.%server_hostname% --letsencrypt-plesk:plesk-secure-panel
