how to get Previous row of a gallery using power apps?

[mkmaheshkumar]

suppose I have a gallery with one rectangle and one status label. The gallery has four rows. If the previous row's status is 'approved' and the rectangle is filled with color Orange, then the current row's status is 'approved' and the rectangle will be filled. If the previous row's label status is 'pending' and the current row's status is 'approved', then I want the rectangle to not fill. See in the image, the first row is 'pending' but the others are 'approved' with the rectangle filled. I want the user to restrict step by step when the first row's status is 'pending
