Snom D865 - Display BLF PickUp Popup - How?

Hello!

I need help to set our D865 Phones to Display a Message with Pickup Notification. Additional to the BLF-Led Status (it is working fine). Other Manufacturer call them Display BLF PickUp Popup (Fanvil) or Pickup blf visual (Yealink).

If i am informed correct, Snom has similar functionality. Can someon help me to set it correctly? What is the correct Option Name and how is it to set?

I tried to search the Snom documentation.

I find only a Phone Status called CallForPickupAvailable. When i set it in status_msgs_that_are_important with Value CallForPickupAvailable:10/3, it shows me only a warning under the Info Button. Without information who is the caller and the called Person. There is a Text to accept the call, but with which Button? And the most important - there is no calling information and does not pop-up on the display.  Is is not the same as by other Manufacturer - not really Visual BLF Pickup Display.

Thank You!
