Skoda Karoq wiring diabram

I am looking for a wiring diagram, mainly with the layout for the kessy system, looking to identify all the connections involved with the starting.

I enter my car, the dash states - welcome - but when I press the start button, The ignition does not come on.

I have checked all of the fuses, but nothing blown.

I was thinking that I should start working backwards from the start button and see if there is a place of no power ???

obviously I cannot do a diagnostic as the ignition will not come on.
