iOS Stickers?

Has anyone bundled stickers with an existing iOS app?

I added the sticker extension in Xcode and put a test image in, built, then launched on my phone but nothing showed up in iMessage.

Because Unreal handles project settings, packaging…before I go further, I thought I would ask:
Are stickers supported/possible?
If so, can someone tell me the steps I need to take to add them to my app via UE4?

Hi Beastman,

We do not officially support Stickers at this time but it may be possible to include them on your own via XCode:

Creating Stickers for iMessage

In the mean time, I have entered the following feature request to officially add this functionality to the engine, if possible. You can track the status of this request on the following link: UE-42171
