Stucked in Mani Menu!

in PlayerController i want to add a main menu from begin play then on start button is pressed i want to remove this widget and add the MainHud which have the health bar, ammo count to display, but i don’t know how to get the refrence of the start button in C++

I really don’t think it’s worth the effort when you can just scroll down to the bottom and add an event for On Pressed and then add call an OpenLevel node.
