Media Gallery population with Velo

Question:
How to populate “Media Gallery” database field items with Velo/Code?

Product:
Wix Editor

What are you trying to achieve:
I need to populate and control media gallery files in UI.

What have you already tried:
Populating in repeater, using progallery, wix-pro-gallery-backend, media manager

Additional information:
I need to populate media gallery files from specific item in database. My goal is to map it in repeater, and from there i can display images & delete/add them. Deletion and adding them is not a problem for me, problem is displaying them. I cannot find a way to do that with code. If anyone can guide me which is the correct aproach, maybe some samples would be appreciated.

Thanks!
