An admin wants to deploy certain pages in Order Management to approved mobile devices. Which two steps are the recommended approach for this?

The recommended approach for deploying certain pages in Order Management to approved mobile

devices is to install the Salesforce mobile app from Apple Store or Google Play and save the pages

with the options of both Desktop and Phone applied. The Salesforce mobile app is designed for easy

data access on the go. You can view Order Management record pages on the mobile app, but you

can’t access its console features, like screen flows. To make a page available on the mobile app, you

need to save it with the options of both Desktop and Phone applied in the Lightning App Builder.
