How do you use Dock Widgets for plugins?

I'm fairly new to plugin development and I'm having some trouble with the new DockWidgetPluginGui thing where it creates pop out windows, I'm trying to make a personal plugin where I can edit properties of a part as a test because I'm working on my first plugin, but I don't know how to make it so the window is visible when they click the button.

So far, I have it to where it shows up in the toolbar with the button there and an image but it creates the window when I load up studio, how do I make it so when you click the plugin button it shows the docked window and when you click it again it will close? I don't think there is a property of it called 'Visible' like regular frames and I'm stumped.

local toolbar = plugin:CreateToolbar('')
local button = toolbar:CreateButton('Property Adjuster', 'Adjusts properties.', 'rbxassetid://208075646')

local ChangeHistoryService = game:GetService('ChangeHistoryService')

local info = DockWidgetPluginGuiInfo.new(
    Enum.InitialDockState.Float,
    true,
    false,
    250,
    250,
    250,
    250
)

local interface = plugin:CreateDockWidgetPluginGui(
    'Property Adjuster',
    info
)

button.Click:Connect(function()

end)
