+ * Gravity Connect // Notion // Radio Button to Date Property Mapping
+ *
+ * This snippet demonstrates how to map a radio button field to a Date property in Notion.
+ *
+ * Instructions:
+ *   1. Modify the filter name to scope as needed.
+ *     * see filter reference for full list of variants: https://gravitywiz.com/documentation/gcn_notion_page_data/)
+ *
+ *   2. Get the Date property ID from the Notion database and update the $property_id variable.
+ *     * Enable the gcn_show_feed_database_debug_info hook: https://gravitywiz.com/documentation/gcn_show_feed_database_debug_info/
+ *     * Open the browser developer console and navigate to a GC Notion feed which is connected to the database you are populating into.
+ *     * Scroll up in the developer console until you see the debug info displayed.
+ *     * Find the date property and copy the ID.
+ *   3. Double check that the date format in the radio field options matches the $date_format variable.
+ *     * Note: if it doesn't, you can either adjust the date format in the radio field options or adjust the $date_format variable.
+ *
