Do you know a project for maintaining sticker packs for multiple platforms?

[blued_gear@fedia.io]

My goal is to have a folder with images + a configuration-file which describes the stickers (file, associated emoji, name, link for sources / artist name) and then an application which can create / update sticker packs from the images for messengers like Signal, Matrix, Discord and so on.

Is there already such a (preferably FOSS) project or service?
