How to connect a second mouse in VirtualBox?

Question

virtual box

Good afternoon. Colleagues tell me how to connect a second mouse in VirtualBox so that it is independent. I tried to do it using USB filters and it works, BUT the mouse cursor is not visible in the OS on the virtual machine. Although in fact it is there. There are no such problems with the keyboard. Can anyone suggest what is the problem. As you already understood, I need to run 2 jobs on 1 PC. Can you suggest alternatives. I tried to set up MultiSit but some libraries need to be updated. I can't do this because the system won't update. Everything is blocked by SecreNet
