Hello Ahmad,
I have not tried requesting a formal recording of a Capability for Work assessment, but have made covert recordings, which I would have been prepared to use if needed.
It is certainly true that most assessors are still working from home, but if you are happy to wait longer for an assessment then it is probably worth another call to the CHDA to see if you can have an assessment with someone who can record them.
