Hide Element if rich text lower than fixed number of characters

I designed a rich text element with an animation that extends the height of the element if you click on read more (weiterlesen).

Everything is working fine.

However, I need to hide the Read More Element if the Richttext from the connected CMS has less than 1000 characters.

anyone knows how to? help appreciated.
