the backpack item is not displayed, even when it is enabled by default

**Steps to reproduce**  
No need to replicate, the configuration I had is already shared and by default the shortcut item is activated. 

**Expected behavior**  
I would expect it to show me the backpack item in the inventory, in this case configured to appear by default in slot 5.

The item is only given to players that have the permission to use the backpack, when changing world, spawning or connecting. If the player is given the permission later, it will only appear in their inventory once they switch world, reconnect or respawn. To make sure the player has the necessary permission they should be able to open the backpack with /backpack open.
