Oracle fusion database table for Context based DFF segment API names

We need to extract API names of context based serial numbers DFF attributes from database table. However, we can't figure the appropriate table which holds these details. We have come across one table which contains display names of attributes but not the API names.

Here is the SQL query for the display names:

select * from fnd_descr_flex_col_usage_vl where DESCRIPTIVE_FLEXFIELD_NAME='INV_SERIAL_NUMBERS'

Here is the navigation to check the API names in the Oracle fusion:

setup and maintenance > global search > manage descriptive flexfields > name= serial numbers > scroll down to 'context sensitive segments' > select context value > edit the selected value to see the API name
