Attestation de départ

Hi, just trying to navigate how to leave switzerland. I have already submitted to ocpm my notification that i will leave geneva a while back. I’ve applied for an attestation de départ but it did not give me an option to choose an address and it doesn’t tell me whether it will send a copy by email. The address on my B permit is outdated, so i’m worried they will send it there. (i am 70% sure I did fill in a form saying i was changing address ages ago but didnt update the B permit because it was mid covid and i just forgot).

Does anyone know if there is an option to buy an attestation and send it to a different address?

Any help appreciated
