An electronic device comprising:

• a processor configured to:
• receive, by a first system process, a request for one or more content item bundles;
• in response to receiving the request, obtain, by the first system process, the one or more content item bundles for presentation of the one or more content item bundles, wherein the one or more content item bundles are inaccessible to an application process;
• receive, by the first system process, a selection of a content item bundle from the presented one or more content item bundles;
• and
• in response to receiving the selection:
• extract one or more content item locations from the selected content item bundle,
• obtain one or more content items from the one or more content item locations, and
• provide, by the first system process and to the application process, the one or more content items of the selected content item bundle.

A non-transitory computer-readable medium storing instructions that, when executed by a processor, cause the processor to perform operations comprising:

• rendering, by an application process and on an electronic display, a first user interface associated with the application process;
• receiving, by the application process, a request for one or more content item bundles;
• in response to receiving the request, providing, to a system process, a request for displaying one or more content item bundles on a second user interface for selection by a user, wherein the one or more content item bundles are inaccessible to the application process, wherein the first user interface and the second user interface are at least part of a third user interface rendered by another system process;
• in response to providing the request for display of the one or more content item bundles, receiving an indication of a selected content item bundle of the one or more content item bundles;
• and
• in response to receiving the indication, receiving, by the application process, one or more content items of the selected content item bundle.
