If you leave too big a gap around it it will not be integrated, it will just
be a washing machine with a door on the front, with an oversized gap between
the adjacent doors
Read the instructions carefully for the hinge positioning, you may have to
drill the door to take the hinges
If it is levelled correctly it will [should] not rattle around.
Never listen to others READ THE MANUAL, if the others give you wrong
information, will they pay you damages if it goes wrong?
