How to use Item in Inventory?

[xyz1337]

Hi Guys,

Trying to figure out how to use Items which are currently in the Inventory.

My main Idea was to use this for the Contract "World Renowed". Something like that:

<If Condition="GetItemCount(55179)" > 5" >
<While Condition="not IsQuestObjectiveComplete(9935, 0)" >
<UseItem Items="55179" SkipMissing="true" />
</While>
</If>

It actually counts the Merits, and if there is enough to get the 1500 renown, it should use them, as long as the Quest is not "complete".
But it seems I might misinterpret the UseItem Tag in this case, and it will not work anyway like this. Also tried it with the ID and some absurd variants.

There was this snap I found in the forum here (which I am using in the RegenBreak, to heal quicker), but I cannot implement it somehow with the Exec Tag in the XML:

string itemName = "Cold Pasta";

InventoryItem item = GameManager.Inventory.Bags.Items.FirstOrDefault(o => o.Name == itemName);

if (item != null && item.IsValid)
item.Use();

Anybody has any Idea?

Thanks

EDIT:

<UseItem Items="55179" SkipMissing="true" />
