How to enable Add-Ins in Windows 10 MS Word 365? - ms-word

Question

I am creating add-ins for MS Word for the web as well as offline versions.
When I try to publish it into an office store add-ins it works fine on Word for web and for offline.
When I try to add that same "Publish.xml" file in a Word add-ins it doesn't work for me.
For reference, I attached my "Publish.xml" file here.
Project Type: Word Web Add-in
Target Framework: .Net Framework 4.7.2
Please look into this and give me a response if anyone has an idea on that.
Publish.xml
<?xml version="1.0" encoding="utf-8"?>
