I need to set uyp my mozello website under my domain in google workspace by creating a cname in google workspace

I need assistance setting up my Mozello website in Google Workspace using my existing domain. My domain provider is not either of the prominent ones (GoDaddy or Namecheap) but I am comfortable providing details. I already have access to my Google Workspace Admin Console and this will be my first time setting up a CNAME record. I am looking for someone to show me how to set up the record correctly, with a friendly and patient guide. With no experience in setting up CNAMEs I require someone to explain the process carefully and take me through each step.
