"Self" property explanation

[SaadBazaz]

Hey, I stumbled upon your repo and tried to use it in a project. (https://github.com/SaadBazaz/auto-corona-graphics-generator) However, I need help in Exporting. I'm using the direct Illustrator COM but there's no reference on how to Export.

In the API you've provided as well (illustrator_2020.py), there's a function: Document.Export( ) But it contains an argument called "self" which I don't understand.

Any guidance would be appreciated.
