Optimizing The Wordfence Firewall

Hey guys, I have a message saying the following: To make your site as secure as possible, take a moment to optimize the Wordfence Web Application Firewall. When I configure and download the .HTACCESS, I get an Installation Failed message of: We were unable to make changes to the .htaccess file. It’s possible WordPress cannot write to the .htaccess file because of file permissions, which may have been set by another security plugin, or you may have set them manually. Please verify the permissions allow the web server to write to the file, and retry the installation.

Would anyone know how to fix this?

The site’s theme is Kadence using Gutenberg. There are a few code snippets which are being used on the site. I’m not sure if these could be causing the issue at all
