Okta API Questions on GetApp Requests

I'm currently working on a project using the OKTA platform and API but have some queries.

1. When making a GET call for List Apps Assigned to User or List Apps Assigned to User, I'm getting a response for all apps added to the OKTA instance, rather than the ones relevant to the current users session. Is there a flag I'm overlooking?

2. When getting the result array for list of applications, it returns all the office 365 'sub-apps' (mail, calendar etc) as child arrays to the parent application. However, these sub-apps in the child arrays don't get returned with image links, which other standard applications do. Now while I could hard code for them, it's not ideal. Any advice on this as well?

Thanks!
