Ferber method and wake window

My wife and I have been doing our best to create some sort of structure or routine with the baby, but its at night where we seem to fall short. This wake window seems somewhat hard to understand and we try to get her to fall asleep within a 60min window...feeding, diaper changes, cuddling, the process repeats. It look nearly 2hrs to get her to truly fall asleep. Is there something we're missing?..Then the misses shows me some Tiktoks of moms with newborns (or so the description says) and they're doing this ferber method..it seems legit and from my own little digging, it seems great..has anyone done the Ferber method with a newborn?
