Is it possible to add a callback (in WWGM toolkit) when CAD tool (CATIA) is launched

Dear Experts,

We are trying to run custom CATIA API from WGM using tookit function:

wwgmtkApplication::executeCustomCommand ()

This is called from initialize() method of custom-dll registered in WWGM (customizationTK).

It's crashing since this initialize() method is getting called before CATIA launched!.

Is it possible to add a listened in toolkit when CATIA is launched or is there any work-around solution?

(WGM 10 + CATIA V5 R24)

Thanks for your time.
