add icon to weblink in the home page

Hey, Thanks for reaching out to us.

You have the option to add Web Apps to a device that is enrolled in Android Enterprise as a Device Owner and locked into Kiosk mode, using Hexnode. The Web apps are applications that will take you to the desired website when opened.
The Web App will have to be added to the App inventory along with the desired URL, name and icon. This app can then be added to the Android Kiosk Policy and pushed to the device. Once the policy is successfully associated with the device, the web apps will appear on the Kiosk launcher. On opening the web app, you will be directed to the desired website.

Kindly use the help link to know more about the same.

Cheers!
