Siemens CombiOven Inner Door Glass

Hi, do any of you guys have a service manual for the above unit, HB86K570B/01 I have replaced door inner glasses on many of the smaller (narrower) versions of this oven, but not on this model. The door on the smaller units comes off by inserting a metal pin in the hinge and the closing the door. I am assuming something similar happens here but not with a pin, and I canot quite see how to unship the door, and the door itself does not look to come apart like the other models, so, I am stuck, any help greatfully recieved,

Thank you Patrick 😀
