Is there an api that can read and save the content of a file type note？

Is there an api that can read and save the content of a file type note, test(await window.note.getNoteComplement()).content is invalid.
I'm trying to integrate drawio with a widget, and I need to read and save drawio-type files as strings.

It may be necessary to confirm whether your window.note is FNOTE so that getNoteComplement can be called.

note comes from async refreshWithNote(note), the file type note test (await window.note.getNoteComplement()).content
is undefined

I think you can get note content from BNote.getContent. And you can create note from BackendScriptApi.createNewNote.
Then you can replace note with new note

Currently implementing in svg format

await note.getNoteComplement() should work, but only for "string typed" notes which is detected from MIMEs. SVG is treated as a string type, drawio proprietary files probably not.
