thanks,
i solved temporarily like this
SWM changes variable "SWM-OP" to 1 on launch, changes to 0 on close
3 finger tap > middle finger action checks that variable for detection is SWM visible with advanced condition
but it has a serious bug. 3 finger tap stucks as middle finger if BTT crashes while using SWM (saw many times. but reduced last versions)
this will not be problem with your fix
