When I do a test I noticed that security headers sees the CSP but not the other type of headers i.e. Strict-Transport-Security X-Frame-Options X-Content-Type-Options Referrer-Policy Permissions-Policy Is there a way to include these other headers? You can extend the CSP served by the plugin using a custom function and hooking in to nunil_output_csp_headers_header_csp with apply_filter()
