You're correct. There isn't one in the OAN just yet. I'm guessing that's because Apple requires MFA for logging in to the Apple DEP page. Currently we just have a SWA config set for our app tile for that reason.
Thank you for reaching out to Okta Support! Currently, the Apple DEP application is not available through the Okta Application Network. As Mike Rossman mentioned, you can try setting the application using SWA. In case you would like to see the application added in the OAN, you can suggest this on the Okta Community by using the 'Feedback’ option at the bottom right corner of the Okta admin console. Features suggested in our community are reviewed and can be voted and commented on by other members of the community, therefore making it much easier for the engineering team to understand the priorities that you have for feature requests. From there, the PM team will review the top 30 most voted upon ideas each month and provide feedback/roadmap status on these via the forum.
Thank you, Cristian Mondiru Technical Support Engineer
