Hide product grid buttons on mobile UI in Prestige Theme

Hi All, just went live with the website www.thebeautifulwatch.com. I want to hide the grid switch button at the bottom right filter/sort bar on the mobile. and let the filter and sort elements fill up the space. Can anyone guide me on the coding edit required for this?

@PRPdc ,

@media only screen and (max-width: 749px) {

.CollectionToolbar__Item.CollectionToolbar__Item--layout {
    display: none;
}

}

Add this css at the bottom of Online Store->Theme->Edit code->Assets->theme.scss.liquid
