Make a widget child, call it “childWidget_Buttons”
Setup this inside your child widget
Then you make this inside the widget thats going to have the button
This allows you to store the buttons to an array, call simulate click, etc…
Use public variables and edit it like (Inside the child widget blueprint) this if you want text on the button etc other important options, and add public variables to what you want to edit on the child button, once added to the parent widget!
