need help with making the attack selection list blueprint

so my level bp is following this order
first i create the battle_status_widget and add it to viewport
then i spawn the enemies and feed them to the add enemies → to the select_opponent widget which also has creates the back_button widget as a child,
so after having it bind in battle_status widget how should i go so that it works and does what i tell it to like in the image of post 37?
