What app is it, as you sould could push it with VPP https://support.apple.com/en-us/102073

Power Apps on the App Store (apple.com) 
its a free app; do I still need to get VPP ? as even on app deployment in jamf pro that option is greyed out

You need a license, a VPP or a user licenese

if it free, its gray out

You need to map the license, to get a device license

it is a free application Power Apps on the App Store (apple.com) that I am trying to deploy using "Mobile Device Apps". The VPP codes tab in the app says content not available to assign to mobile device. May be because it is a free application. 

Do you have a Apple Buiness manager or a Apple school manager

you need to "buy" the license

 yes I do :) 

you then have a licensed edition

if its not too dumb question; can you assist me with an article for next steps ( I am more from Windows world and picking  things up on mac) 

after "buy" the license, you need to control if you have the license here

What do you need now?
If you want to chat I am @AndersDamsgaard on slack  / https://www.macadmins.org/

Thanks a ton; I think this is what I have to do next
