Arcade Attachment() function is in Field calculator as is written in post: https://www.esri.com/arcgis-blog/products/arcgis-online/mapping/visualize-your-attachments-in-arcgis... I would appreciate this function also in Symbology context.
I want to visualize the number of Attachments by color as it is in the post, but live version. If I calculate it in Field Calculator I have the Number at that time, but when somebody adds an Attachment I need to manually calculate it again. I can add an Arcade script to Form in map, but uploading an Attachment doesn't trigger the script in Form. So I need to write the script in Symbology Expression, where Attachment() function is not available.
