Set up subdomain in GCP

I have a domain, www.name.com and also name.com and I want to set up a subdomain, name1.name.com. I registered name.com with Google domains and I set up the website as a project on GCP. I need a step-by-step on how to set up name1.name.com IN THE GC CONSOLE and NOT in the shell because I am just a guy who runs a business and how is too poor to employ the services of a computer wizard and who therefor does it by himself. Thanks a lot for understanding.
