I figured that since the free SSL certificate provided through Plesk also needed a DNS record added to be installed, I would have to send a request every 30 days. If this is not the case then that would definitely be easier. If so, this record can be added instead:
type: TXT
Domain name: _acme-challenge.jarno.helioho.st
Record: QG54NsZqo2yTvOb6H8SKHoGlXinU7ABB_UcJX3A5e8Q
