Outlook Add-in open automatically on load of outlook client (Desktop and Web)

Question

I am working with Outlook office add-ins to achieve the below functionality -

Requirement :
As soon as user open Outlook client (Desktop and web) it should display a dialog or popup with some information on it.

Already Tried :
I came to know from Microsoft references that one way to achieve this is through office add-ins. I have created one outlook add-in in react framework using yeoman office generator. This add-in comes with task pane to show customize content.

Problem :

1. To enable add-in, I have to click on some mail which I don't want.
2. After enabling add-in, I have to click on show TaskPane button from the ribbon to display my TaskPane which I also don't want.

I want to display my add-in TaskPane as soon as user open Outlook. Can someone please help on how this functionality can be achieved. Any suggestions or reference doc will be really helpful.

Thanks!!

I doubt a JavaSctipt add-in can do that.

Create a COM add-in for desktop Outlook and a web browser extension for OWA.
