How can I allow googlebot to crawl my sitemap? .htaccess

So I want google to be able to crawl my sitemap but I don't want other people to be able to see or view my sitemap, here's my current code


Order deny,allow
Deny from all
SetEnvIfNoCase User-Agent "Googlebot" goodbot

<Files "sitemap_index.xml">
deny from all
Allow from env=goodbot
</Files>

Currently this is giving a 403 forbidden error on google search console when I try to submit sitemap.

Solution 3 : Using .htaccess RewriteCond
Change URL in last line to your main site so that your site gets SEO ranking if someone linked in to your blocked site.
