You will get the menu you see in the images above.
With the Basic package you will get just the UI (customized with your logo and game name). But without the background and you will have to code all the functionality of the buttons yourself.
With the Standard package you get the UI (customized with your logo and game name). And on top of that the background. Which will change depending on what submenu you are in. But you will have to code all the functionality of the buttons yourself.
With the Premium package you get all of the above and all the scripts behind the buttons are included. So everything will work without you having to code. To use the option “keybinds” you will have to change your input manager from the default “Unity inputmanger” to a custom one. If you have any questions about the keybinds, don’t hesitate to ask me.
