Hi, it is planned to add in the next update. You will be able to add 1 custom document. We will also surely add more documents as we update the script!
Hi! Data is stored within each unique item through the ‘ox_inventory’ metadata. When you use the item, the script retrieves all the data associated with that specific item, and the functionality revolves around it. Therefore, if you pass the item to another player and they attempt to use it, they will still see the data saved on that particular card making each item unique. Current version : 1.0
