Provide an option to close/delete the add-in in the Excel
Currently there are two ways to delete the add-in:
1 - Select the outer boundary of the add-in and click delete.
2 - Click on the top right corner of the add-in (near boundary) that would bring up the menu and you can click delete.
We've received this feedback from multiple users and now working on providing a more intuitive way to our users to close/delete the add-in.
