Add Lottie Animation into Silverstripe in CMS Editor

Silverstripe Version: 3

How do I add my Lottie Animation code (https://lottiefiles.com/) into Silverstripe in CMS Editor, seems to be discarding it once I save because it contains Javascript. Can I edit the source DB file instead (Where would I find that?), if I can’t use the editor to add Javascript?

Help would be appreciated.
