3d object viewer or transparent lottie

Hi I made a transparent MOV animation video in blender and would like to display it in my Appgyver App.

Previously I was using Lottie Animations for my animation needs, but I cant keep the transparent background this way.

This is the link to my lottie file:
workout on Lottiefiles. Free Lottie Animation

Does somebody has any idea how I can integrate my animation into Appgyver or remove a background from a lottie file, making it transparent?
I have my animation as dae or fbx and can render it to a transparent MOV file.
