Why can't I customize quick action and add to Page Layout in the New Note Taking tool?
|Knowledge Article Number||000240905|
|Description||Customers may have noticed that with New Note Taking tool enabled, they are not able to create/customize the quick action and add to object page layout.
At the moment, this is work as designed as the feature only have an out of box quick action and this default action is only available in lightning (LEX).
May use Triggers/VF/lightning component if needed.
