Hi Divya,

As a further notice, there is also the alternative way of providing the
event_filter config statically (instead of the dynamic way via the
sculpt_manager).

In order for this to work you'd need an individual *.sculpt file for
your platform (see [1] and [2] for how this works). In this file you can
then reference your static event_filter config file, like it is done in
[3] (the corresponding config file is [4]).

Cheers,
Martin
