Hello @reuvygroovy
The Taskbar in Windows 11 is very limited compared to the one in Windows 10, currently, there is no native way to show the second line of icons on the taskbar. The good news is, Microsoft has listened to the Insiders that tested Windows 11 and they are adding new functionality to the Taskbar and so we need to wait for that in upcoming updates to Windows 11.
Meanwhile, you can try some tools to make this possible.
