How to control the window size when using pane:move_to_new_window()

[Alien-lv426]

Hello, I have the following hotkey defined to move a tab into a new window. This works well, but often the new window appears very large so the first thing I have to do is resize it. Can anyone suggest how I can set the position and size for the new window please?

{ -- Move pane to new window
    key = '!',
    mods = 'CTRL|SHIFT',
    action = wezterm.action_callback(function(win, pane)
        local tab, window = pane:move_to_new_window()
    end),
},
