Google wake windows for newborns and follow it religiously. You should see results soon. If I’m not wrong newborn’s wake window is only around 45 mins to an hour.
I only found out about this after my nanny left at 6 weeks. Prior to that my son kept crying in the evening and I thought it was colic, but end up it’s because he is overly tired. Nanny advised not to let baby sleep from 3 plus 4 pm so that baby can sleep at night. That was an absolute mistake as baby was already overly tired by then since bedtime was at 7 plus. So please try to follow wake windows and see if your situation improves
