Using After Effects PNG sequence in Edge Animate

I would like to incorporate an animation that I created in Adobe After Effects. I have rendered my work as a PNG sequence.

I have imported the sequence into Edge Animate.

I believe that the trick to making the PNG sequence play as intended, is to code the stage such that each element in Edge Animate plays for a specific duration, disappears and then the next element appears. This continues until the last element is played and then the stage holds this last element on the screen.

The big Q is - what's the code? Any help will be greatly appreciated.
