WEB AR - Selfie Wall - Workflow

Dear 8th Wall, my question is simply related to the most effective suggested workflow for a project (Web Ar - Selfie Wall) we are currently developing with the following requirements: media(image and if can also video) recorder and sharing function from within the app, use of front and back camera, body segmentation/occlusion and for content development the use of video textures, simple 3d, animations, textures…etc.

While for content we see the studio editor with great benefits, we are uncertain how the other functionalities which would need to come from app.js and body.html code working in the legacy mode editor - can be implemented.

We are open to recommendations where this can be done. many thanks for the help.
