How to send email to multiple recipients using SendGrid (ToEmail - CSV)

Using the SendGrid Connector, how do I format the ToEmail field if I want to send an email to multiple email addresses? The description says "Comma separated list of email addresses to send the mail to."

 

I am building a csv list of email addresses while Fetching the list of users in a Scribe Organization. The list is a string variable in the following format: {email1}, {email2}, {email3}

 

However, when I use that string variable in the ToEmail field of the SendGrid Connector, it is only sending the email to the first email address in the list.

 

Is there some other format I should be suing that the SendGrid Connector supports?
