This project uses the Element icon https://github.com/userstyles-world/userstyles.world/blob/2f6a31cc73168796ce7962fee56c122e9001e30b/web/views/icons/element.tmpl for the Matrix contact option. Matrix provides icons including SVG at https://matrix.org/branding/. I suggest switching to decouple from a single implementation, similar to how one wouldn't use the thunderbird icon to represent email as a whole.
