How to properly handle links from google docs?

The task is to write an editor that will understand the links that are added via the Google dockshere

So we added a link to the Google Doc then copy entire row and pasting it in textarea, the word is underlined should be the same link as in Google docks.

If you just insert a row in the textarea then it will be plain text. There is the idea that Google adds some sort of hidden symbol and maybe it can somehow see through JS ?

Prompt in what side to dig .
