The addon is very good (Cell r221-release from April 6th 2024).
I play on the Chinese version of Lichking Classic (version 3.4.x). I'm testing the addon and noticed that it does not respond to the absorb from the Sacred Shield spell (ID 58597), however, it correctly responds to the absorb from Valanir's proc (ID 64413).

Please tell me where the addon determines what exactly is an absorb spell? In the addon's lua code? Or in the built-in libraries? Or does it take information from the Warcraft libraries themselves? How can I fix the situation, please help.

I also want to note that for some reason addon won't let me press the Heal Absorb button.
