Uploads from Existing Azure Container Not Showing Up

I installed a theme on a fresh site then connected an EXISTING container from my clients live site. I am able to upload new images to this container, but none of the existing images that are already in the container are showing up in the media library. Only images from the theme’s dummy data are showing up (and any new images I upload.) How can I get my hundreds of images to show up in the media library? Thank you!
