Green Screen / Chromakey in iOS

I'm a teacher at a school with 1:1 iPads, and we're considering purchasing Adobe software. In my review of Premiere Rush, I was surprised that Chromakey was not a feature in 2023. Even the iMovie app, which we are using currently, has this feature, but otherwise is very basic, hence the move to some other software.

Please consider adding the Green Screen / Chromakey feature to mobile apps. Thanks.
