citing a text message

I recently had a chat with a family member who wanted me to find out the birthdate of an aunt of hers gave me background information in a text message and I wasn't quite sure how to cite it. I based the citation below on EE 3.42 similarly to an instant message. Does this seem correct or do you have suggestion on how to improve it?

Dee Hendrickson, Cape Coral, Florida [phone number,] to Desiree Hendrickson, text message, 11 January 2020, 3:00PM, "Background information on Agnes Young; privately held by Desiree Hendrickson, [phone number, street address] Sunny Isles Beach, Florida.

thank you.
