php - How to save ACF custom fields data when a plugin triggers the WordPress save_post hook

I have a plugin which is triggering thesave_post hook of WordPress upon creating posts. The plugin is a scrape plugin. I need added some code tofunctions.php file which should save the data once thesave_post hook is triggered by this plugin.

What my code is doing:

1. Fetches the data from one of the fieldshowtoapply.
2. Puts the data after formatting it as required into the new fieldapplication_email using some PHP code as you can see below.

Right now, without using thesave_post hook, the acf fieldapplication_email data is not saved in the postmeta table. However, upon clicking edit the post (which refreshes the post), the data is saved without even having to click on the Update button.

How do I run this code when thesave_post WordPress hook is triggered by the plugin because only then can the plugin save my custom fields data alongside the data being crawled.

The code:

add_filter('acf/load_field/name=application_email', function( $field ) {
        $howtoapply = get_field( 'howtoapply' );

        
            $apply_link = get_field( 'howtoapply' );
            $link       = $apply_link;
            libxml_use_internal_errors( true );

            $dom = new DOMDocument();
            @$dom->loadHTML( $link );
            $dom->loadHTML( $link );
            foreach ( $dom->getElementsByTagName( 'a' ) as $a ) {
            }

            function cfDecodeEmail( $encodedString ) {
                $k = hexdec( substr( $encodedString, 0, 2 ) );
                for ( $i = 2,$email = '';$i < strlen( $encodedString ) - 1;$i += 2 ) {
                    $email .= chr( hexdec( substr( $encodedString, $i, 2 ) ) ^ $k );
                }
                return $email;
            }

            if ( ! is_null( $a ) && is_object( $a ) ) {
                $field['value'] = cfDecodeEmail( $a->getAttribute( 'data-cfemail' ) );
                $GLOBALS[ $field['value'] ] = cfDecodeEmail( $a->getAttribute( 'data-cfemail' ) );

                if (!add_post_meta(get_the_ID(), 'application_email', $field['value'])) {
                //update_post_meta(get_the_ID(), 'application_email', $field['value']);

                // Update field in database
                update_field( 'field_123456', $field['value'] );
            }
                
            } else {
                
            }
        
        return $field;
    }
);
