Generate id for heading and get heading text to set as the value of id -- Ckeditor5

[guosuqian]

I am trying to generate heading id automatically in the editor instead of configuring all id manually for heading . I need to get the heading text to be the value of id attribute. But I have no idea about how to develop the plugin

(1) how can I get all heading element and get all heading text
(2) How can I set the id attribute to the all correspond heading element

Anyone who is able to give me a little start to get this to work?

version： "ckeditor5": "43.3.1",
