Tachometer For Street Twin 900

Pardon wise peeps !!!

I've just bought a (used) 2022 Street Twin 900
I was slightly disappointed to see that apparently it does not have a tachometer (?!)
Although I haven't taken delivery of mine yet, I thought I would do some research and look at the Owner's Handbook online ...
The Handbook makes reference to a Tachometer on page 39, but ...
There is no mention of how to display it - i.e. 'scroll' the display to get it ...
Obviously until I have her in my garage, I can't play about to see/learn how the display works ...
I don't really want to have to buy and install an aftermarket Tacho, so please can a wise person explain what I've missed ??? - Thanks.

Chris.
