Wix studio : How to get rid of video lateral scroll bar in html embed

Question:
How can I get rid of the scroll bar / line in my html embed displayed via rich content ?

Product:
WIX STUDIO

What are you trying to achieve:
I created a section grid with 3 columns, inside of which I added a CMS rich content container in each columns.

My rich content is a html embed of this type :

<div style="width: 100%; aspect-ratio: 9 / 16; position: relative; overflow: hidden;">
  <iframe
    src="https://player.vimeo.com/video/XXXXX?autoplay=1&loop=1&muted=1&background=1&badge=0&autopause=0&player_id=0&app_id=58479"
    frameborder="0"
    allow="autoplay; fullscreen; picture-in-picture; clipboard-write; encrypted-media"
    style="width: 100%; height: 100%; position: absolute; top: 0; left: 0; border: 0;"
    title="XXXXX"
  ></iframe>
</div>

I get this bar on the right side, and I don’t want it !

Anyone knows how to get rid of it ?
Many thanks !!

What have you already tried:
Tried to add the “overflow:hidden”, change stretch in the section, change the size in the rich content box…
