What is the white Bookmark icon?

This Bookmark feature is a function in the UNUM app to see how a pre-planned photo/video grid will look on the already-published-to-IG portion of the UNUM feed (with the IG icon watermark).

Just drag and drop a chosen unpublished grid to the bottom part of the UNUM feed and it will automatically duplicate it as if it's published on your IG account. You can also change the watermark into a collab post, pinned post, or a Reel. This gives flexibility on visually planning your content.

Once it's all done, you an always tap and delete it.
