View mail in browser link

I’m looking to eliminate the use of a newsletter management tool in favor of sending from CRM via campaigns.
I can’t find the functionality to insert a link in the body of the email that gives the recipient the ability to open it in the browser.
I’ve checked in the url trackers but there is only the one for opt-out, I’ve checked in the email templates management but I can’t find anything…

Any ideas on how I can create the link for the web version of the email?
