Figma REST get images only returns one image URL

Hello,
I am using the Figma REST API to get images with a URL like so: https://api.figma.com/v1/images/[file_id]?ids=[frameID1,frameID2,frameID3, etc.], but the response only contains 1 image URL. How can I get 1 URL for each frame i passed in ids?

Looks like a similar issue here but it went dead: Not getting frame images separately
