Autoplay video on productpage on mobile with "Trade" theme?

[JT95]

Hi. I have a video on my productpage ("Trade" theme). On desktop it autoplays, but on mobile not. I've found several other posts, suggesting to add mute, autoplay etc. attributes in the code. However, I'm not skilled with editting codes, and the suggested codes are all for different theme's. Therefore my question, if anyone can help me do this in "Trade" theme? So the exact folder in the code, which part of the code I have to edit and to what.

Thank you very much!

A little javascript would do. Need to select the video element and play it on load which would make it look like it is on autoplay.
