Lounge Access with New Account?

Hey there, I just got approved for a new Sapphire Reserve card today (currently traveling in Mongolia). The primarily impetus outside of the great rewards is to gain Chase Lounge access on my 6 hour layover in Hong Kong International.

How can I set up my Priority Pass account without my full credit card number? I’ve added the cc to my digital wallet but that’s been about it.

Thanks in advance!
