I got the r3 in yest says I am running off 4.0.20 firmware but the newest is 4.0.23 so I am not on the new update and there’s nothing saying update in the router on my pc

So just got the r3 in yest took it out of the box was wondering if I need to do any update on it firmware on there now is v4.020 I see the newest version is 4.23 or something like that but I can see no where to update the firmware on the r3 even hit the top right 3 dots like I did on the r2
