We would like to fetch other player's character's inventory, so a player can view what loadout other players are using (similar to how it works in Destiny 2 for example). The only API calls I've found regarding this are:
https://blog.playfab.com/documentation/client/method/GetUserInventory (this only seems to return the inventory for the logged in user)
https://blog.playfab.com/documentation/client/method/GetCharacterInventory (this only seems to work for characters which are owned by the logged in player)
