How can I make an npc give you an item after a "DialogChoice" is selected?

I have been wondering, if a certain dialog is selected, then can I like make the NPC give you an item?

Part of script that needs an "Item Giver" part to it.

script.Parent.DialogChoiceSelected:connect(function(Player, Choice)

if Choice.Name == "DialogChoice" then

--- Item Giver Script

Also can this work on a custom dialog? I can still wonder... Custom Dialog

Basically once a certain text is done (on keypress [E]), the NPC gives you an item.

Regular Dialog

Same thing as the custom dialog but just using the regular dialog.

NPC giving you items

This part is the main script. I tried using one of those "Giver" scripts but that didn't work out too well if I could have some help I would greatly appreciate it.
