Digitally singned file with different PAdES levels (LTA, LT, B)

SUMMARY
According to https://www.etsi.org/deliver/etsi_en/319100_319199/31914201/01.01.01_60/en_31914201v010101p.pdf there are 4 signature levels: LTA, LT, T, B. It would be fantastic if Okular could recognize (and show) those levels in signatures. Attached documents have signatures with levels LTA, LT and B. Levels with 'T' in their name have Timestamp component as part of signature and LTA has additional document timestamp.

STEPS TO REPRODUCE
1. Open PDF digitally signed with different signature levels (e.g. LTA, LT and B) 

OBSERVED RESULT
There are no details for Advanced Signature

EXPECTED RESULT
Advanced signature details should be shown to user

Adobe Reader doesn't seem to show that (unless I failed to find it), so kind of low priority wishlist in my opinion
