Connecting QU pad to QU 24 via airport express

Hello this will probably be straight forward but when It comes to networking and ip addresses I’m completely lost

My church has just invested in qu24 and I’m looking to connect my iPad Pro, I purchased a airport express and wondering is there a step by step guide to do this, I understand ip addressed have to be in same range and have tried using manual but still not getting connected

Grateful for any help or pointed in right direction

Good luck.
