B777 Pax Oxygen System Flow Rate

Hi all,
I'm seeking specific data on the passenger gaseous oxygen system flow rate (in L/min NTPD) for the Boeing 777-200ER/300ER across various cabin altitudes (10,000 to 43,000 ft).
I understand Boeing provides a table detailing oxygen flow rates for different cabin altitudes, enabling operators to build descent profiles tailored to their specific operations.
Does anyone have access to this table or relevant excerpts from Boeing documentation?
Any insights or references would be greatly appreciated!
Thanks in advance,
