Have 99 Honda Odyssey (LX)

Outside (passenger side) sliding door handle broke off (like an idiot I
tried to yank door open when it was frozen shut after heavy snow/ice storm).

I ordered a new one - came today

Now - how do I get an the inside of the guts of the door so I can take-out
the remains of the existing door handle? It is not obvious to me how the
inside paneling comes out.

All help appreciated.
