You are now able to decrypt sticker's (including animated stickers):

      let mediaData;
      if( message.type==='sticker') {
        let stickerDecryptable = await client.getStickerDecryptable(message.id);
        mediaData = await decryptMedia(stickerDecryptable);
      } else {
        mediaData = await decryptMedia(message);
      }

      fs.writeFile(filename, mediaData, function(err) {
        if (err) {
          return console.log(err);
        }
        console.log('The file was saved!');
      });

Note: This is an Insider's feature for now and requires a license key.

can you explain in more detail what this does?

@MarsVard Without this, the decrypt method will result in a transparent empty webp file as that is the background of the sticker.

With getStickerDecryptable, the actual sticker message is retrieved which will allow the decrypt function to output the sticker (including an animated sticker).
