Problem with plugins

I’m trying to have to make a GUI pop up when you click a plugin button. I know that the parent of the GUI is changing when the button is clicked, however, it is not visible and I can’t figure out why. I think their may be an issue with the way I’m creating my interface, but I can’t figure out what because I’ve never make a GUI for a plugin before:

local Interface = plugin:CreateDockWidgetPluginGui(
	"Panel",
	DockWidgetPluginGuiInfo.new(
		Enum.InitialDockState.Float,
		false,
		false
	)
)

I think the issue is that you need to specify the minimize window size and default window size of your plugin. Here’s the documentation on DockWidgetPluginGuiInfo!
