need help with mitered dominos

I designed a small stool for my son with child safety in mind. Flared out legs, 45 degree corners and small. I came up with what i thought to be a simple project using dominoes for the joinery. but now after i cut the parts, i don't know how to set up the domino for accurate cuts on this particular piece. the leg aprons are mitered and will be joined to the square part of the leg which will no be mitered. initially i thought i would reference the tops of the boards but it turns out i don't have enough room and i would cut completely through the apron even with my smallest domino. i would like to have a 1/8" reveal. does anyone have any idea how to set this up to be repeatable for all 8 joints. Thanks in advance

Also, my domino came with the attachment for mortising end grain of narrow boards but i can't seem to figure out how to attach it. any help there will be much appreciated as well.

So the board thickness adjustment needs to be set so the domino is more towards the center of the stool or towards the inside of the board.  If you want an 1/8" reveal after you cut the mortises on the aprons change the depth by 1/8" or 3mm. You might want to do a trial piece to nail everything down.

I'd probably set the depth of my domino to a 35mm or thicker board to ensure the domino stays in the apron I can't remember the exact stops on the domino though you don't need to use them and could use the other gauge. Also i wouldn't plunge any further than 15mm in the apron.

I put a red line to illustrate slightly exaggerated though.
