Does library supports Contextual Alternates (calt)?

[WhitePhoera]

Trying to use that library, mostly managed to what i was needed.
Then i moved to test with more advaned font(ex. FiraCode), and found that it's ligatuges is not used.
In FontForge i found that enabling use of calt table fixes == into single character.

Is there is some setting i miss in Typegraphy library to use those tables or there is no support?
