Ideal Standard Conceala 2 dual flush repair parts Updated!

This is a fix to repair the back of the two flush button pumps that had broken off the back of the faceplate, leaving the mechanism the wall behind.
It's a long shot that someone might need this, but the work is already done so here it is.

Just pull off the thin plastic pipe attached to the button assembly leading to the plumbing (don't lose the pipe in the wall) then put the button assembly into the repair part and assemble as in the picture.
I used superglue it seems fine, assemble first
