Detecting / adding a unique User Agent for the in-app browser

Hey everyone, I am wanting to display certain pages or posts in from my website using my websites theme, but i want to be able to hide the header and footer. I’m using the Divi theme and it has the ability to add display conditions to show or hide sections/rows/modules etc based on browsers and devices. With the help of a developer I’ve been able to add a custom browser agent to the list and want to know if the AppMySite app has an already existing custom user agent attached to its in-app browser (and if so, what is the user agent ID) and if not, is it possible to have a custom user agent added/created. If this can be done than I will have much greater control over the layout of embeded and fully styled divi pages and posts within the appmysite app.

Yes, I’m trying to find out the same thing. What is the User-Agent name so I can style target the style of my site for users that are using the app.
