Hi ,
I am Ivan, I will help you with this.
I'm sorry, but Windows 11 has the function for you to maintain a separate task bar according to the application on each screen.
Start Menu > Settings > Personalization > Taskbar > Taskbar Behaviors > When Using Multiple Screens > Main taskbar and Taskbar where window is open.
Thus, keeping the applications that are on the main screen in the taskbar and another on the secondary monitor would be this function.
Alternatively, you can also return to the Windows 10 taskbar if you wish in Windows 11 using a third-party application.
Hope this helps.
If you find the answer helpful, please mark it as an answer.
