Replacing Hehr sliding window handle gasket??

[rgnprof]

I have a good-sized side sliding Hehr window.  The long handle that runs along the edge popped off as the rubber gasket came loose.  It looks like this is just a press fit - get the gasket over the edge of the window and then the handle 'presses' on over the gasket.  I have a new rubber gasket piece - trouble is I'm at a loss as to how to to get this handle pressed back on.  And yes, I'm trying to do it without taking the window out...

Anyone have any tips?  I hope...
