Integrating CK editor into a retool app

I (Non-tech PM) am with the help of a dev, trying to replicate our internal panel in retool. For the most part I can see that it will work and have been able to replicate quite a bit of it already.

There are 2 things that I have not found any information on:

  1. CRON generator - Is there any way i can directly integrate some cron generator into my retool app. For now I have just provided a link to a third party website and given in put field to put the CRON expression

  2. CK editor - We use CK editor to create notification templates for our notification service. Although we havent really tried anything to integrate CK editor into retool, I have not found any resources suggesting that this has been done before

I would greatly appreciate any help for the above 2 queries.
