In classic mode, if we write "example.com", it creates automated link like :

   

     <a class="vglnk" href="http://example.com" rel="nofollow">
         <span>example</span>
         <span>.</span>
         <span>com</span>
     </a>


**What I tried:**

 - I searched about it and found that `class="vglnk"` comes from Discus
   Plugin and we need to disable an option to do that.  But it will affect another affiliate links so I could not proceed further. [![enter image description here][1]][1]
 - I tried to search about HTML entity for 'dot'. so that we can use
   that sign so that wordpress does not take it as a link. But that sign
   converts into '.' itself
  
 - I tried to add that link in `<!-- wp:html -->example.com<!-- /wp:html -->`..it did not work
 - I tried to add `<pre>example.com</pre>` but still it is not working

I want plain text of example.com, please assist me.
