Help with events after dialogue

Hello! I am relatively new to Gdevelop and was testing things out. I wanted my player to talk to this NPC of which after a little tween animation plays where an object shows and gets deleted after. However, when I did a preview the object does not show? I’m guessing it’s because of my eventing? Is there a way for events to happen if the dialogue is completed? Here is my events. (The reason why the condition is blank is bc idk what to put there.) (sorry for bad english it is not my first language)

You show objects, and you delete them in the same event block, so at the same time.
Please take some time to learn how the GDevelop event system works. We have tons of tutorials and a wiki.
