[ Missing content status on inject ] - not clear enough

[EllynBsc]

Description

When adding an inject, I get a 'missing content status', this status is not clear enough. What kind of input am I missing ?

Ex: For an email inject: Title + body is mandatory

Suggestion solution

List clearly what input are mandatory for each inject for us and display in a tooltip to the user what content is missing to allow the status to be enabled for that specific inject.
