Best way to check if a record is newly created(in my case opp) in process builder through Conditions are met option

Hi Community, I have a scenario where I have couple of "Conditions are met " criteria to evaluvate to trigger a flow or when an opp is newly created. so I am trying to evaluvate this as just one more condition by using drop down but I am not sure how can i check if the opp record is created newly and if so trigger the flow in that scenario as well. Can someone help with this? I am exploring formula and other things at this point
