CSS for "dot" list in live preview

Hi. Need help changing the “dot” in the list to a “dash”

Also a line-height change in the code for the standard Obsidian theme, in Live Preview mode

.markdown-source-view.mod-cm6.is-readable-line-width .cm-content {
  line-height: 1.2;
  padding-top: 5px; 
  padding-bottom: 5px; 
}

.cm-formatting .cm-formatting-list .cm-formatting-list-ul .cm-list-1 .cm-s-obsidian .cm-formatting-list {
  list-style-type: "-";
}

Can anybody help me, please?
