Customizing sitemap.xml location with Jekyll plugin

I would like to know if it is possible to customize the location of the sitemap.xml when generated with Jekyll sitemap plugin.

By default it generates it in the root of _site folder (so when we access it from the browser we find it at: https://website.com/sitemap.xml) but I would like to customize it so that it is generated in f.e _site/index (so that in the browser we find it at: https://website.com/index/sitemap.xml)

If possible, how can I do it?

Thank you!
