Hey,

Maybe you also can descripe how to get the long press on the Siri remote configured on a Logitech Elite Hub remote?
I can add a new device Harmony Pro TV, long press the Ok botton to get the same function - but cant manage to get it to work under devices (where it's only possible to select the "Select/Ok" function from Harmony Pro TV - and that dont work).

Thanks
