How can I add comment on the diagram, not just include comment?

Hi there,

I have an issue on using dbdiagram.
I want to add comment on the diagram so that I can view the diagram and comment together,
how can I do this?
I know I can use [note: “This is how much being listed”],
but I’m not only need comment in the schema, but also on the diagram though.

Table products {
  id int [pk]
  name varchar
  merchant_id int [not null]
  price int [note: "This is how much being listed"]
  status varchar
  created_at varchar

Could anyone help? Many thanks!
