+ * Gravity Connect // Notion // Add Relation Property From Dropdown
+ * https://gravitywiz.com/documentation/gravity-connect-notion/
+ *
+ * Instructions:
+ *
+ * 1. Using GP Populate Anything, populate a Dropdown field with the IDs of Notion pages you want to relate to.
+ * 2. Create a Relation property in your Notion database that you want to populate with the selected page IDs.
+ * 3. Configure the Usage Example below to match your form, feed, dropdown field id and relation property name (this much match the relation property name in Notion exactly).
