For those wondering about the published procedures, here is the link to AIP Nepal:

The only approach plates I could find for VNPR are in AMDT 2/2023, coming into force with AIRAC cycle 2/23 on Feb 23, 2023. Nothing for RWY 12, apparently.

The current pages, which came into force on Dec 29, 2022, do not include approach plates yet.
