I am using Enhanced Emails.
My use case is as follows: When on the contact record, if the user clicks the send email button, they can send the email, and the "Related to:" field is filled out with the appropriate contact record ID. This is then reflected on the activity history (probably the most important part)
This works perfectly fine on any other object, say on an Account, if you send an email on the account object to someone, it is reflect on the "Related To:", filling it out with the AccountId and is put into the activity history.
The issue is that Contact doesn't appear to be something you can select on the "Related To:" field. Is there anyway to add this?
