There Should be a Warning When publishing to whatsapp

[SweetJenna]

I work sometimes very hard, and keep testing using the preview popup testing thing, only to deploy on whatsapp and realise that block isn't supported with whatsapp.

For e.g. the javascript code block. There should be a warning in the block itself or at the least while publishing to whatsapp it should warn us script block etc doesn't work on whatsapp.

Even a static warning would help.

Please please add some sort of indication except the docs, I'll be very grateful.
