Telegram imported stickers don't show up on GitHub pages and Android

Hello

I have succesfully implemented this widget to my desktop instance, but trying to use the sticker picker on Android phone (Android 14, latest version of Element app downloaded through Aurora store) I only get empty pictures with alt text showing up instead of the real image.

I wonder whether this is a permission issue since I would rather like my stickers to stay private, the only thing I haven't figured out is if I need to approve another Element instances to show aswell and how to approve them for other users in my groups.
