Kindly help me to create CSR for subdomains. I already followed this link(https://experienceleaguecommunities.adobe.com/t5/adobe-experience-cloud-questions/how-to-generate-a-...) and they are suggesting to use openssl which i am not sure if it is secure. Also i am not aware if i can do this in aem cloud if this option is there as i dont see anywhere to create CSR in aem as cloud except for Domain setting and SSL settings ,please let me know.
