Are the properties zotero-key and zt-attachments mandatory?

[dcgk]

Hello!
I am excited to discover Zotlit! After years of being frustrated with the limitations of Nunjucks templating with Zotero Integration, I am here hoping to create a smoother workflow between Zotero and Obsidian.

Starting with the zt-field.eta I was going to set up my properties, but soon discovered that there are two properties that I am not abel to edit: zotero-key and zt-attachments
Are these properties mandatory? Is there any way to change their name?

I keep my YAML organised using the pluggin Metadata Menu, does anybody have experience how to itegarte a Metadata Menu fileCalss into the zotlit template zt-field.eta?

Much appreciated and many regards from Spain!
