Hi,
You should use the native "Multi-app kiosk" profile template in the Intune portal rather than manual XML/OMA-URI configurations. This profile uses Application User Model IDs (AUMIDs) for the calculator and Microsoft Edge to act as unique identifiers, creating a restricted sandbox that blocks all non-essential system interfaces. This method is the preferred, modern standard for ensuring that warehouse devices remain secure and dedicated strictly to your inventory web application.
Hope this helps :)
