How can I change carousel arrows?

Hello,

I would like to change the arrows used to navigate the carousel from '-->' to '<' '>'. The transparent background should change from round to square and could be a bit smaller. How can I make these changes?

I would greatly appreciate your assistance!

button[class*="_arrow-button"] svg, .mobile-arrows svg {
    display: none !important;
}
button[class*="_arrow-button--left"] div:before, .mobile-arrow-button--left:before  {
    content: "\e006";
    font-family: 'squarespace-ui-font';
    transform: rotate(270deg);
    display: block;
    font-size: 30px;
    line-height: 60px;
}
button[class*="_arrow-button--right"] div:before, .mobile-arrow-button--right:before {
    content: "\e006";
    font-family: 'squarespace-ui-font';
    transform: rotate(-270deg);
    display: block;
    font-size: 30px;
    line-height: 60px;
}

Thanks @tuanphan, that works for me. I would like to color the arrows in the carousel section white. Can you help me with that?

Change code to this

button[class*="_arrow-button"] svg, .mobile-arrows svg {
    display: none !important;
}
button[class*="_arrow-button--left"] div:before, .mobile-arrow-button--left:before  {
    content: "\e006";
    font-family: 'squarespace-ui-font';
    transform: rotate(270deg);
    display: block;
    font-size: 30px;
    line-height: 60px;
color: white !important;
}
button[class*="_arrow-button--right"] div:before, .mobile-arrow-button--right:before {
    content: "\e006";
    font-family: 'squarespace-ui-font';
    transform: rotate(-270deg);
    display: block;
    font-size: 30px;
    line-height: 60px;
color: white !important;
}
