My RMA request got approved but I don't have the wraith spire cooler, I misplaced it, can I just send the CPU? or it won't work that way?
You don't need to send the cooler, actually, AMD asks you to don't send the cooler.
You can check other tips from AMD for how to return your CPU here: https://www.amd.com/en/support/kb/faq/rma-01
At the end of the page (Shipping Guidelines n. 3) you can see that AMD asks you to "Avoid sending the heat sink and fan".
