How do I autorun Excel Office Add-ins

[abhipritkumar]

I have developed one Office Add-ins in Java script. I have installed this add-in in Excel.

The current issue is with the trigger of these add-ins. So we need to manually trigger the add-ins.

https://learn.microsoft.com/en-us/office/dev/add-ins/develop/automatically-open-a-task-pane-with-a-document -> This thread says how to automatically trigger the task pane, but this property needs to be set at the document level.

Our requirement is that the add-ins task pane gets triggered automatically when any document is opened (new or existing). We don't want users to interact with the add-ins.

There should be no overhead for users to interact with add-ins. Is it possible?
