[Question] What is the proper syntax to include this in the starting inventory?

[Winddbourne]

I want to provide my players with an Enchiridion starting book for my mod pack. But when I use the automatic function the mod detects only the "create new book" item, rather than all the tags. If I use MT hand on my book this is what I get:

enchiridion:book.withTag({identifier: "Getting_Started"})

How do I translate that into something the config file understands? It isn't:

enchiridion:book.withTag({identifier: "Getting_Started"})

When I put that in I get an error: Java.lang.numberformatexception: for input string ""getting_started"})"
