How to change vertical separation between button icon and text

Godot Version

4.7

Question

I have a button where I want the icon to sit centered above the text. This works perfectly fine by setting the icon’s alignment, as seen in the screenshot. However, I want them to sit closer together, but once in this orientation it doesn’t seem like there’s any way to change the separation between the icon and the text. Changing the button’s h_separation value in the theme does nothing, and changing the stylebox’s content margins moves both of them together. Is there any way to do this?

I feel like the only way to do that is to do it in a external editor. Of course, there may be a way to do that, because I’m new, but I don’t think Godot can change it. Use Canva or something to change the vertical seperation.
