How to set the initial text content of a text box through a plugin

1

The official tutorial shows how to set the initial text content of a text box by setting the doc property when creating an EditState.

let content = document.getElementById("content")
let view = new EditorView(document.body, {
  state: EditorState.create({
    doc: DOMParser.fromSchema(schema).parse(content)
  }),
});

My question is, can this process be implemented through Plugin.

for example:

let initDocPlugin = new Plugin({})

let view = new EditorView(document.body, {
  state: EditorState.create({
    schema: schema,
    plugins: [initDocPlugin],
  }),
});

No, the document is determined solely by the doc option. Plugins cannot change this.
