Spine 2d exported Atlas

I exported files from Spine 2d and got .atlas, .spinejson, and .png.
Is there any way to make the Spine scene use the .atlas exported from the Spine 2D program?
Right now, the .spinejson works — I tried creating a new .atlas in Defold and dragged in all the raw image files I needed, animation works fine.
The only issue is with the atlas file.
Can anyone please help
Thank you.
