According to this Ask Ubuntu question, the default workspaces setting in Ubuntu 22.04 is "primary monitor only": that is, only the primary monitor switches workspaces; the rest of the monitors stay static. You can change that setting to allow all monitors to change workspaces at the same time in the settings app under mulititasking, as described in the answer to the above-linked question. There is no option to allow all monitors to switch workspaces independently of each other.

To be clear: Windows only allows switching workspaces on all monitors at once, MacOS allows you to switch workspaces on each monitor independently, and Ubuntu 22.04's Gnome allows you to switch all monitors at once OR only allow workspaces on the primary monitor. You can't switch each monitor independently. You can only choose to have workspaces only on the primary monitor, or switch workspaces on all monitors at the same time.
