How to make OAM file Transparent in Indesign?

Hi everyone,

So I am trying to put an oam file with a transparent background in Adobe Indesign. The problem is, when I please the file is in in design, the background is white. The oam file is created from adobe animate. When I use the publish settings in animate, I follow all the right steps and make the poster image transparent checking off all the right boxes, etc. but the background still shows up white in in design. I don't know what to do, I'm so stressed and I spent hours trying to fix this problem. HELP!
