Thanks!

Thank you for your responses. 

Just so that everyone knows, there is a way to do this in your web browser. Get the app pulled up via web browser. You can actually turn just about any web page into an app that you can save to your desktop, tool bar, start menu, favorites, etc...for easy/quicker access directly to the destination that you saved.

1. Click the 3 dots on the top right side of the app, and “Open in Chrome”.
2. When open in Chrome, click 3 dots on the top right side of Chrome, 
3. Hover cursor over “Cast, save and share”.
4. Click on “Save page as app”.
5. Title the page/app and click on “Install”.
6. Find the app by searching your computer by the app name that you just created.
7. Save it to the destination of your choosing. I.e., desktop, tool bar, start menu, favorites, etc…

I hope this helps!
