Sutton in Ashfield registration office

Has anybody registered their baby at the Sutton in Ashfield registry office inside the library? I need some help. Im taking my son their next week to be registered however I’m visually impaired and struggle with signage and am not great in places I’m not familiar with. Could someone please tell me which floor the library is on and once I’m inside the library, where do I need to go to get to the office? I can’t find anything online that tells me. And I don’t want to look like an idiot on the day 😂 I know I’m overthinking it. It’s one of my traits I’m afraid 😂
