Where can I get Offfice 365 Microsoft Store version not the Click-to-Run? [closed]

We had developed a VSTO add-in for PowerPoint. So far (From 2007 - Present) our users are able to install our add-in on traditional MSI base Office (2010,2013,2016) and the Office 365 with Click-to-Run based installation technology on both 64bit and 32bit versions.

But recently Microsoft has started to push a new version of Office which comes preinstalled with some Dell and Surface laptops and on this version our add-ins fails to install. The reason as you can see in this Knowledge Base article from Dell is that this Office comes as a Microsoft Store Application. Some Office add-in vendors are recommending to remove this and use the Clik to Run version. Here Andrei Smolin from Add-in Express mentions some problems with this Store version of Office.

I know that this version of Office is not completely built from scratch and it will eventually support VSTO add-ins. I need this version of Office for my development environment so I can make the software ready for upcoming changes. I've tried to find this new Office 365 Microsoft Store version but I ended up getting another Click-to-Run based office even from the Microsoft Store app.

How can we get this Microsoft Store version of Office without buying a new Laptop?

After a lot of finding, I was finally able to get the programs using the Office app.

Here is the about page screenshot of the app.

You can install the Click to Run version by going to My account tab. And finally, if you need the Office 365 Microsoft store apps go to Programs tab and install the required office apps (Word, PowerPoint) from the Office 365 programs category.

Here is a screenshot for that.

Please note that the latest Office app does not include these tabs on my other PC so it might not be available for you as well. I was able to get this version from a Dell OS Recovery Image.
