Where it is used?

WBP_InventoryAndChest
WBP_CraftingMenu
Open the widget where you want the actions/keys to be displayed.
Add "WBP Keys Bar"
You will find the name of the action below. "IMC_InventoryAndCrafting"
IMC_InventoryAndCrafting
This is the name of the action that you must enter for it to work.
If the name is wrong, nothing will be displayed.
You can also use other "Input Mapping Context" but ensure that it is assigned when the controller/character is initialized.
Actions must have a "Display Name" otherwise saving/changing them cannot work [for the key settings menu].
