Videos on listing

Hi everyone.
I am looking for help on a technical side of things.

I have my first ever FBA/private lable/amazon brand listing created. I added photos and a video to the listing when I was creating it.

I now need to change that video as i have a better one but when i go to “edit listing” it only gives me an option of uploading other images but not video. And I cannot seem to find any other options or ways to add the video.

Is there anything to be done and how?
May be you had that experience?

Thank you so much and good luck to everyone, lots of sales.

Aya
