Hi,
Might it be possible to add arXiv ?

Here is a suggestion

		"_icon": "https://raw.githubusercontent.com/arXiv/arxiv-base/66b85f1c9a750d0f631f3762a9c3b467a50ace0a/arxiv/base/static/images/icons/favicon.ico",
		"_hidden": false,
		"_urlTemplate": "https://arxiv.org/search/advanced?advanced=&terms-0-operator=AND&terms-0-term={z:title?}&terms-0-field=title&terms-1-operator=AND&terms-1-term={z:DOI?}&terms-1-field=doi&terms-2-operator=AND&terms-2-term={rft:au?}&terms-2-field=author",
		"_urlParams": [],
		"_urlNamespaces": {
