Importing from After Effects to Animate

I'm making a clip in adobe animate but there's an effect that I was only able to achieve in after effects. I'm trying to export the clip from after effects back into animate but ever time I try, the clip either imports as a static image, the clip imports as a small no-fill square, or the clip imports fine and is viewable and moves on the stage but won't becomes invisble or doesn't render in the quick render preview or the full render file. I've tried exporting the clip as .mp4, .mov, .gif, converting an .mov to a .flv, etc. but none of it works. How do I export this clip to be usable?
