Roof Drain Filter?

An informative on page 43 of my UK owners manual states:

"Remove leaves or other matter that may accumulate on and around the convertible top. If leaves or other matter block the drain filter, water may enter the vehicle. Clean the drain filter at least once a year."

Anyone one where the drain filter is and how it is accessed?

There are two drain holes at the rear corners under the bonnet (hood), there's no cover or grille over these so quite big leaves can go down them that enter from around the screen. The drains seem to end up at the bottom of the A pillar and can be seen with the door open. I have a leaf visible in one of mine but not sure how to get it out other than prodding it with a thin rod. Need to get underneath first.
As far as I can see these aren't mentioned in the manual.
