Cover page / remove display video play button

Site URL: https://plum-octahedron-jxxd.squarespace.com/

Hi everyone,

I am creating a new website via Squarespace platform. The template is Heights.
https://plum-octahedron-jxxd.squarespace.com/
Password to access is: 1234

On our cover page, as you can see with this screenshot: https://ibb.co/RzFZ4Yr
A button “play” appears when we mouse hover below the text.
It’s an error that might come from the cover page style that is made to host a video. However, I didn’t upload any video on it. Only using text branding.

How I could do this?

Thanks a lot for your kind help!

Fix it? I don't see the play button. 

Hi Derrick,
Thank you for your help!
This exactly as on the screenshot that I provided, just below the paragraph / text. When you mouse hover 🙂
Still want to fix it.

Okay, got it,  what cover page are you using? If it is a landing page and not a Heights page, you can't code it.  Might need to switch that is why I ask. 

This is a landing page: from Heights, it's "Premier".
I can insert some code/ custom on it 🙂

Could someone help with this please?

Add to Cover Page Settings . Advanced > Header

<style>
.sqs-slice-play-button {
    display: none !important;
}
</style>
