Question (not an issue)

Sorry if this isn't the right place to ask, but I'm not sure where else to pose this question.

So I'm working on a plugin myself and need to get the ItemId for a series.

This is the only plugin that I've come across that somehow gets said Id for a particular file. That said, I can't seem to understand where/how you do it lol. Could you point me to the place in this repo that you pull that ID from Jellyfin? I would greatly appreciate it!
