Create a portainer image

Hi, I was wondering if someone could help me. I’ve discovered this and would like to use it on a form so that users can upload a video intro of themselves. They can preview the video and once happy they can submit it, then it would go to a storage of my choice.

It seems Uppy could do what I need. I have a synology with portainer installed. I have managed to install a few things following excellent guides from MariusHosting.

However sadly there is no guide for Uppy. Could someone help guide me to install this via Portainer, so I can achieve a video upload via a form (currently using a self hosted formbricks for my forms)

Please be gentle, I’m not that technical but can follow guides.

Thank you in advance.
