I know little about Confluence macros, except that I know there are at least 3 different ways to build one. And the way you are building will be critical information for the Atlassian developer community to help (Bentley says, “Category, category, category”.) Is this a Java plugin for Confluence Server/DC? Or is this a Connect or Forge App for Confluence Cloud? Sorry I can’t answer regardless of the approach, but I hope extra details would someone who can.
