Hi
Thanks for your answer I will test your solution when I need a callback in a function again ^^
Basically the origin of my problem is that I created full verse UI because I need to call on data in the latter
But the button that I created is not usable with a controller
So my current problem is to know how to read data on the verse in a umg or how to create totally custom ui buttons interactable by the controller
But I will create another post for that
