How do you activate different types of blocks?

Good evening everyone,

I am having trouble on how to activate some types of blocks. I am trying to make an app that will add an item to a list when you press a button, and another button that will delete a selected item. The block on the top is easily fitting into the Button1.Click event trigger, but how do I activate the second block?

add the createElement to the list, and set the listview.elements to list.

Would attaching the ListView1.CreateElement block to the set block work?
Like this:
