Bosch Oven Connection

[Jim123K]

Hi I was planning to install a new Bosch oven into my new kitchen cabinet. Thought it would be an easy process considering cooker outlet plate and 45A switch are already there, but seems that Bosch aren't keen to supply any cable (or installation information) with the oven.
I spoke to their customer services and they reluctantly told me that I need to connect a cable by removing an access panel on the back with a T20 Torx.
So now I've bought a suitable cable, I plan to wire this directly to the cooker outlet plate. Now I've noticed a large earthing symbol and arrow on the top of the housing, pointing to a smaller earthing symbol on the back with a shaped panel hole (see images).
Is someone able to suggest what needs to happen regarding this additional earth point?

It's an offence not to provide adequate instructions.

In the absence of any instructions, I'd say nothing needs to happen - there appears to be an obvious earth terminal under that plate:
