Hide certain credit card logos on drop in form

I’m not great with CSS. Can someone help fix this code to hide certain credit card logos on the drop in form? My attempt is not working.

<style>
[data-braintree-id=”unionpay-card-icon”]{
display: none;
}
[data-braintree-id=”jcb-card-icon”]{
display: none;
}
</style>`
