My company website is hacked by the Japanese keyword hack. How to delete XML sitemap full of spam hacks?

[ganapathy11]

My company website is hacked by the Japanese keyword hack. We have cleaned almost everything (By deleting our .htaccess file from our site and uploaded default version of the .htaccess file). Now our XML sitemap has many spam links listed. We cannot find a way to delete/clear it. We tried turning off Sitemaps and then back on. We have reinstalled Yoast. Here is the XML sitemap link - ​https://scgroup.global/sitemap.xml

Any advice please?
Please see the screenshots.

Okay. Will definitely do that in future. Thanks!
Just to let you know that our developer restored the website with backups.
I guess, the issue is due to "Wordpress version 5.7.1". Our developer team is missed to update security release "WordPress 5.7.2" on timely manner.
