I want to use the WP Icons. How can i increase the size?

Hi, I want to use the WP Dashboard icons within my site. Then use them as Anchor links to various locations on the page.
I found the icons here - https://developer.wordpress.org/resource/dashicons/#dashboard

However when i try embed them with the Upfront Code element and pasting for example this code

<span class="dashicons dashicons-dashboard"></span> the icon appears really really small in the upfront editor and dont appear at all on the live site? How can it be scaled up to the same size as the link above? e.g. 30px by 30px ?

After that how can i anchor each icon to the corresponding title area? as they are not images i cant use the embedded settings link. (had some trouble setting this up in the past. Could you walk me through the solution please?)
