Increase size of play button

I've received a lot of feedback from customers saying that they didn't realize our promotional video was a video because they didn't see the play button. Is there a custom code that I could use to increase its size? You can see my website here https://beyondadventures.co/. It's the video under "Who we are".

@lenaentrekin icon is image. So first you need to download play icon and increase its site.

then add these code to Home > Design > Custom CSS. Replace url below to new icon url.

.sqs-video-wrapper .sqs-video-overlay .sqs-video-icon {
   background: transparent url(//assets.squarespace.com/universal/images-v6/damask/play-button.png) center center no-repeat;
   height: 100px;
   width: 100px;
}

5 minutes to check & found the code.

That doesn't work but this does:

.sqs-video-wrapper .sqs-video-overlay .sqs-video-icon {

   background-size: 88px;
   height: 88px;
   width: 88px;
   margin-left: -44px;
   margin-top: -44px;
}
