Great idea design ;-) This will be really nice when completed.
Ok, what I would do here is this… ( I’m a carpenter, so you could play about with this suggestion to suit)
Your center cabinet space protrudes out by the width of your door… say 18mm?
Right, you could rebate both sides in by the 8mm thickness of your mirror, and since I am unsure what material you are using here as the cabinet - Painted wood, or Melamine faced chipwood, you could either paint that sawn/routered edge, or glue/iron on the 18mm X 1mm edging tape - to cover up the cut edge… Painted black so it wont show through mirror.
This would leave the top, and bottom, still protruding, and the bottom would act as a sorta ‘Prop’ to hold the mirror up, and the mirror itself would sit flush with the doors, and have a white ‘Border’ top and bottom.
You could easily play about with fixings for the monitor to bring it forward enough to sit flush with the mirror… and use some kind of cardboard sheet, colored black, all around the outer edges of the monitor to hide the outer framing of the monitor, (that black cardboard will not really be seen behind the mirror anyway.)
To actually hold the mirror in place, there are quite a lot of brackets in the market to suit…

AND/OR…
If you then cut the top and bottom in, by say 3mm, you could attach a flat piece of Single/ Double round moulding beading… say 25mm - if your cabinet is 18mm thick?
That will hold your glass in place.
Obviously you would then have to compensate that 3mm depth into your sides… making them 11mm rebated…
edit… The trouble with using any kind of Glue with 2 way mirrors is that the glue/silicone can react with the film on the mirrors… and with some mirrors, the glue will show through as a smudge… I already looked into this, and the glue would only be an option if the glued edge would be covered by some kind of edging… so the glue would not be visible fron the front.
That MirrorBond is great - For normal Mirrors… because of the silver backing… so you wont see the glue… But on a see through 2 way mirror…
