Edit: I just realized the Samsung Members app does not allow links. To recap, go to the Samsung Galaxy Store and search for Always On Display. If your phone is compatible, you can download it there.
Hey @Seriousfreedom ,
If your phone is compatible you can find it in:
Settings > Lock Screen > Always On Display > On
