chromium-browser --user-data-dir=/home/pi/.config/chromium/weblink https://chrome.google.com/webstore/detail/virtual-keyboard/pflmllfnnabikmfkkaddkoolinlfninn

OR

Under assets, create a webpage link by name "chrome store", type:webpage and link address

https://chrome.google.com/webstore/detail/virtual-keyboard/pflmllfnnabikmfkkaddkoolinlfninn

Deploy a playlist with this link to be displayed on the screen

2. With a mouse click on the add extension button on the screen

Note: By default extensions do not run in "incognito" mode. So please uncheck "Reload link URLs each time"  option under Group settings for the keyboard to work
