Submit the Blogger Blog's Sitemap to the Google Search Console

In many articles, I have found that I can submit the blog of my Blogger blog by submitting

"atom.xml? redirect = false & start-index = 1 & max-results = 500"

as my sitemap url. When I did this, I got a URL error stating that it could not be retrieved.
I also tried myblogaddress / sitemap.xml.
None of it works.
And the old search panel indicates that this is pending.
Now, Google automatically indexes part of my page randomly. So I have to manually enter all pages in the URL check and see if they are indexed and request the index.
It takes so much time. It will be very helpful if I can use a sitemap.
