Update address for mail delivery of PR card

Hi, I have just landed (after COPR) but not received the physical PR card yet. I had given a temporary stay address during this, and now have found proper long-term stay. Where/how should I update the address, so they mail the PR card to the new address?

I tried the common form on IRCC website using both UCI and COPR number, but it says application not found. (And I suspect because it is no longer an ongoing application).
