@rayakoren I believe in order to get the latest icons we would need a monaco update (codicons are contributed by the @theia/monaco-editor-core).

• export jar uses the export icon which is not available in our version

You can view our codicons.css by the following path:
node_modules/@theia/monaco-editor-core/esm/vs/base/browser/ui/codiconLabel/codicon/codicon.css
