BG77 PoLTE(Positioning over LTE)

Hi,
I’d like to find out more about PoLTE on the BG77 module, but I can’t find the Document
Quectel_BG77xA-GL&BG95xA-GL_Positioning_Over_LTE_Application_Note” mentioned in the AT_Commands_Manual in the Download zone.
Where can I find this document and is there any additional information available regarding PoLTE?

Thanks
