Can I ask PIP PAPER ASSESSMT,not on members Guide?

Hello dear fellow members,

I would like to request a PIP PAPER-BASED ASSESSMENT instead of their phone assessment.

I am confused though because -
no offence intended as I am very grateful for help and guideline on this forum -
I cannot find on the members guides anything that says we can request a PIP paper based assessment instead of a phone assessment,
(unless I am not looking at the right guide).

Yet on this forum a few times, and I am very grateful for it, it is mentioned that we are more likely to be successful if we can get our GP or other medical professional to write a letter that says exactly that I would suffer ‘Overwhelming Psychological Distress) if I were to have a phone assessment.

— I would be very grateful if someone would guide me to the members guide that confirms the above, if there is one.

Ps I Would very much like to as for a paper based PIP assessment instead of the phone assessment because of overwhelming psychological distress even though I do not take depression and anxiety tablets and my disability increases my anxiety/depression (so maybe I would not be successful on that ground even if my GP provided me with that letter)
and also because of all my lower joints are full of osteoarthritis, I need now a hip replacement, knees replacements, have OA on lower back, have very severe valgum knees, my legs are severely deformed, torn knee meniscus and much more but a cam impingment on one hip makes it impossible for me to sit down and flex my hip and painkillers cannot control my pain and I know a phone consultation could last 1 hours maybe more, but me I am constantly in pain and cannot see myself coping with a 5 minutes telephone assessment let alone 1 hour or more.

Any help would be greatly appreciated.

Best of luck in your assessment if you have one due!
Good health to you all!
