[help need!]modification on ExportMDFileHeaderV2

[StrongThighs]

Just have a go to modify the default template for the YAML header. Despite the fact that i have deleted the "collections" part, the itemKey, LibID etc. remains in my header. Grateful if anyone could offer any insight.

${{
  let header = {};
  header.tags = noteItem.parentItem.getTags().map((_t) => _t.tag);
  header.date = new Date();
  header.yr_publication = parseInt(noteItem.parentItem.getField('year'));
  header.author = noteItem.parentItem.getCreators().map((v) => v.firstName + " " + v.lastName).join("; ");
    return JSON.stringify(header);
}}$```
