Detecting when Roblox Studio is closing (in a plugin)

According to the docs, Plugin.Unloading should detect when the place closes - but by my testing this is false.

Create a local plugin with the following code:

plugin.Unloading:Connect(function()
    local part = Instance.new("Part")
    part.Name = "Unloading"
    part.Parent = game.Workspace
end

On a Team Create place, when you close + reopen you’d expect a part called “Unloading” to exist in the Workspace, but there is not

Any other ways to detect in a plugin when studio is closing?
