After your 2 yr GC which is conditional you must file a Removal of Conditions ROC which is a 10 year GC. You must file a ROC or you will be out of status. ROC is much more involved than the AOS so start gathering your documents throughout the two years. FYI visit my January 2022 I-751 Filers and you'll get an idea what you are in for in two years from now. Also it's very the filing fee is going out soon, but nothing you can do about that.
