New Lenner Homeowner - Need Help

[Him2]

Hi. We recently moved into a Lennar home and we that the home has 3 Access points in the house. We were told to download the Ruckus Unleashed app and begin configuring. Since we’re not the first homeowners there’s no Configure.Me WiFi. There’s also no sticker in the panel with log in info. Previous homeowner also doesn’t have any info. We are not tech people in any way so hoping someone can help provide step by step instructions for starting from the beginning. Assuming we have to reset everything?
