Alidropship Sitemap.xml

#1
Got a few queries on alidropship plugin:
1) in alidropship settings (SEO), when we activate the sitemap.xml and robots.txt, does it mean this will auto-generate these 2 files? When will they get generated automatically? Where can i find sitemap.xml?
2) Also hear that file sitemap.xml needs to be uploaded into the domain root folder of our website and then add this sitemap URL to google search console. Is this mandatory to improve SEO?
Thanks!
