Looks to me like the membrane has been removed (white lining attached to egg shell).
@SliverBirds gave good advice ... put it in a "container" within the incubator & leave it alone, my concern is the membrane I see that has been removed & all those veins, it's not ready. I maybe wrong but perhaps applying an artificial membrane; tissue coated in coconut oil or there's this "paper tape" (for people allergic to bandaid adhesive) coated in coconut oil. Not knowing where the beak also a concern but that tapping is it attempting to pip. Will tag some I know may be of help here ....
