I've got hacked and the hacker added redirects ( HELP PLEASE )

Hi There,
My website got hacked and the hacker added thousands of html redirects and google dettected all in the search console.
I already deleted those links and clean by doing a full backup restoration, the fault was my dump developer left the admin panel open as wp-admin and added a pssword of admin123 the most stupid guy I ever met,
but I need your help guys. How can I make google know that this is not what I wanted to do and was not intentional and was hacked? is there any way to ignore all this or send it googlee?
Thanks a lot guys

You should clean the website (hosting files, CMS core file + DB) first > Ensure the website is clean > Submit fresh Sitemap to GSC

1. Check your hosting file manager, check all the files which were recently modified.
2. Check if you had taken a backup earlier which can be restored
3. The best way to do is to reinstall the CMS and restore the latest backup

if you have done it correctly then don't worry
