I believe they put desiccant in the separator channels.

Correct, and chances are it is ruined because of the moisture that it
has already been exposed to. Sealing the hole by whatever means is
just gonna lead to fogging/condensation down the road.

Flushing the window with dry air can also dry out (regenerate)
the desiccant, if it's done slowly with a $5 aquarium air pump
and a $5 timer.
