go to this above directory open the file and change noindex to index this is located in header line

public function headers() {

$charset = get_option( 'blog_charset' );

header( "Content-Type: text/xml; charset=$charset", true );

header( 'X-Robots-Tag: index, follow', true );

after doing this just index this page manually from google after some day this will be index directly and google will crawl all pages

For Rank math

includes/modules/sitemap/abstract-xml.php

protected function send_headers( $headers = [], $is_xsl = false ) {

$defaults = [

'X-Robots-Tag' => 'index',

change no index to index in X-Robots-Tag
