Unsuccessful at removing custom unicode bullets from showing up in Accordion block

This is the code I have for the custom bullers and what I found for removing them, albeit unsuccessfully :

ul li>*:first-child::before {content: "➤"!important;color:#ED1C24;font-size: .85rem }
.accordion-item__title{color:#3673a3}

.accordion-block li:before {
    display: none;
}

If you still need help, you can share link to page where you use accordion, we can check easier.
