There are plugins available for embedding posts from Instagram, Twitter but I am wondering how to go about embedding page from Notion to the text editor? It might also require OAuth for user authentication. How would you guys build the functionality like this to enhance the text editor(plugged in from TinyMCE).

As shown below in the picture, this is a form for user to write the book summary and share with others. I want to add a button by which the user can directly pull the page content from notion to text editor. I've checked the documentation of notion API and the page will be redirected after OAuth and it doesn't seem possible to inject the fetched data to the same ejs file.
