I didn’t exactly understand what you wanted, but I did know that you needed custom styling. What exactly do you need? Something like this?
.cm-hmd-internal-link {
color: var(--text-on-accent) !important;
background-color: var(--interactive-accent);
padding: 1px 8px;
text-decoration: none;
border-radius: 14px
}
.cm-hmd-internal-link:hover {
background-color: var(--interactive-accent-hover);
text-decoration: none;
}
.cm-formatting-link {
display: none;
}
Or do you mean something else?
