This tool is available at the public Galaxy server https://usegalaxy.eu.
It is not installed at https://usegalaxy.org (yet). I believe there is a request to add this already to .org, but if not, will create the request ticket and link it back as a comment so you can follow progress.
If you want to install it into your own local/cloud/docker Galaxy, then most of the general admin help in this other post would also apply in your case: https://biostar.usegalaxy.org/p/28949/. The only difference is to use the function Admin > Tool Management > Install new tools.
Thanks! Jen, Galaxy team
