Pulling dynamic fields from Shopify JSON into email template

We’re creating a personalized email flow for post-purchase where customers receive a “thank you for ordering” email as soon as they complete the purchase. The email will contain…

1. order line info
2. delivery date

We’d like to pull the delivery date into a dynamic field within the template. Writing {{ event.extra.note_attributes}} returns the below…

[{'name': 'calendar_type', 'value': 'product'}, {'name': 'Date Format', 'value': 'mm/dd/yy'}, {'name': 'product_42275060383907', 'value': 'Dyed Black, Double Shredded Mulch |&| 07/28/2023 |&| Friday'}, {'name': 'Do you have a driveway', 'value': 'yes'}, {'name': 'Dump Location', 'value': 'Top Left'}]

We’d like to grab just the delivery date within the following name and value:

'product_42275060383907', 'value': 'Dyed Black, Double Shredded Mulch |&| 07/28/2023 |&| Friday'

Is it possible to write syntax to grab this value or should we look for a different approach?
