Add conditional to Trigger based on if user is new or returning
When setting up a trigger have a select option to "show for" everyone, only new users, or only returning users.
This will allow us to customize certain actions for different types of visitors. Tawk already logs this information of if they are new or returning.
This could go further than this conditional into adding more conditionals but this is one I see being very useful and Tawk having this info already makes it doable from my perspective.
