Further to keyplyr's comment about the time it takes. I just launched two new sites over the past couple of months. In both cases it took well over a month before any usable data was available in GSC (Google Seach Console). Now if the site is already operational and getting traffic and you simply open an account, my guess would be that it will be faster to populate.
Analytics provides data immediately. But if you open a new account for an existing site it will only show data from the time the account was opened.
