Missing Documentation for String-Based Permission Values

In this documentation, permissions are represented as integer values such as (int) 1 = read; 2 = update; 4 = create; 8 = delete; 16 = share; 31 = all (default: 31, for public shares: 1).

However, when performing a PROPFIND operation, the permission information returned for files is in a string format (e.g., SGDNV, SRGDNVCK).

The correlation between these string and the integer values is missing.

According to my tests

SRGDNVCK → Can Edit
SGDNV → Custom Permission only Edit
Also, SGDNV → View Only

We need to know which custom permission is active for a file based on its string value on the client side, so that we can implement this feature.
