In Studio, How do I use invoke method to insert an item at the beginning (index 0) of a list?

Hello,

I am just simply trying to use the Insert method to add an item to my list at index 0.

However, when I try to invoke method of insert on list, before I even add arguments I’m met with this error:

Could anyone demonstrate how to use the invoke method for insert?

Assign Activity
YourList = YourList.Prepend(YourItem).toList
