how would i get a StyleBoxFlat from a resource to be a node's "override theme"

[flat onyx]

Try add_theme_stylebox_override(name: StringName, stylebox: StyleBox)

[flat onyx]

Are you trying to copy the StyleBox from one node to another's?

Try```swift
func _ready():
add_theme_stylebox_override(&"the_override_name", character_details.skill_button_ui)
