Pulling first name from email contact in Outlook for Mac

Trying to pull the first name from the recipients email and paste into my email such as:

Hello {{FirstName}},

Have found many useful scripts for the native Apple Mail, but wondering if anyone has a script optimized for Outlook for tips on how to modify it? I'm using Outlook 16.74.1

I don't use Outlook, so I can only give a guess at a method, but my first go for this would be something like:

Tab or Shift-Tab to get to the Recipient field.
Tab or Shift-Tab to get back to the content field.
Use the Search using Regular Expression action to find the first name (probably just ^\w+ will work for most cases).
Insert Text

Note that people do not necessarily have a first name.

Will give that a try, thank you!
