Hello fellow travelers!

So I have my Chase reserve card and I have a flight tomorrow with a couple of layovers. Does anybody know how I can access the priority pass lounge is which is a benefit of this card? Do I need to wait for them to send me a card or can I just use the app? Thanks for any help. So I have my Chase reserve card and I have a flight tomorrow with a couple of layovers.
