ListView TinyDB Delete Update Listview

I am new in Kodular.
I have created the blocks in the photos attached.
There is a listview and used TinyDb to store my data.
I would like when I longClick on an item in the listview to pop up a new dialogue with three button: delete edit cancel
so when I press on delete it delets the item and when I press on edit it lets me edit and save
Could you please give the blocks in how to create that in an easy way.
