How to set image URL from user's meta value as WordPress Avatar throughout entire site?

I have a feature that allows me to upload images from the settings section of the woocommerce account. The function comes from here: Add a profile picture (file upload) on My account > edit account in WooCommerce

I have a feature that allows me to upload images from the settings section of the woocommerce account. The function comes from here:

Everything works correctly, however there is a small drawback. The avatar is not applied to the comments section of posts or product reviews.

So since the function is updating the data of the image metakey, I was thinking of setting this metakey as the universal value from which wordpress has to get the image url. This way I believe that the uploaded image is also displayed in the comments and reviews sections.

Can anyone help me with this ?

Here's what I'm trying to do, but it doesn't work:

The code below I got it from: https://gist.github.com/tripflex/3190b9b3b484f99c0a4ba4f6c59cb44f

<?php
add_filter( 'pre_get_avatar_data', 'smyles_set_avatar_based_on_user_meta', 10, 2 );
function smyles_set_avatar_based_on_user_meta( $args, $id_or_email ){

    // Set this to the full meta key set in Save As under Auto Populate tab (for WP Job Manager Field Editor)
    $user_avatar_meta_key = 'image';

    // Check for comment_ID
    if( is_object( $id_or_email ) && isset( $id_or_email->comment_ID ) ){
        $id_or_email = get_comment( $id_or_email );
    }

    // Check if WP_Post
    if( $id_or_email instanceof WP_Post ){
        $user_id = $id_or_email->post_author;
    }

    // Check if WP_Comment
    if( $id_or_email instanceof WP_Comment ){
        if( ! empty( $id_or_email->user_id ) ){
            $user_id = $id_or_email->user_id;
        } elseif( ! empty( $id_or_email->comment_author_email ) ){
            // If user_id not available, set as email address to handle below
            $id_or_email = $id_or_email->comment_author_email;
        }
    }

    if( is_numeric( $id_or_email ) ){
        $user_id = $id_or_email;
    } elseif( is_string( $id_or_email ) && strpos( $id_or_email, '@' ) ){
        $id_or_email = get_user_by( 'email', $id_or_email );
    }

    // Last check, convert user object to ID
    if( $id_or_email instanceof WP_User ){
        $user_id = $id_or_email->ID;
    }

    // Now that we have a user ID, check meta for avatar file
    if( ! empty( $user_id ) && is_numeric( $user_id ) ){

        $meta_val = maybe_unserialize( get_user_meta( $user_id, $user_avatar_meta_key, TRUE ) );

        if( ! empty( $meta_val ) ){

            // Set to first value if returned value is array
            if( is_array( $meta_val ) && ! empty( $meta_val[0] ) ){
                $meta_val = $meta_val[0];
            }

            // As long as it's a valid URL, let's go ahead and set it
            if( filter_var( $meta_val, FILTER_VALIDATE_URL ) ){
                $args['url'] = $meta_val;
            }

        }
    }

    return $args;
}
