WooCommerce variable Meta box product pricing - wordpress

Question

I am creating a multi-vendor site using WCFM at the moment. I'm trying to recreate the UI from a plugin I saw somewhere but integrating the metabox I made with WooCommerce is the challenging part.
Essentially I want the vendors to just enter the prices for variations than to do it manually by adding the attribute then save it as a variation etc. I have all the metabox plugins. This is the code I have for the recreated metabox:
<?php
add_filter( 'rwmb_meta_boxes', 'yb_flower_price_box' );
function yb_flower_price_box( $meta_boxes ) {
$prefix = '';
$meta_boxes[] = [
'title' => __( 'Flower Price by Grams', 'yb' ),
'id' => 'flower-price-by-grams',
'post_types' => ['flower', 'product', 'product_variation'],
'storage_type' => 'custom_table',
'table' => 'Flower price',
'fields' => [
[
'name' => __( '1 gram', 'yb' ),
'id' => $prefix . '1_sm7qy7uyf5',
'type' => 'text',
'size' => 3,
'columns' => 1,
],
[
'name' => __( '2 grams ', 'yb' ),
'id' => $prefix . '2_btw3zbak44j',
'type' => 'text',
'size' => 3,
'columns' => 1,
],
[
'name' => __( '3.5 grams', 'yb' ),
'id' => $prefix . '3.5',
'type' => 'text',
'size' => 3,
'columns' => 1,
],
[
'name' => __( '7 grams', 'yb' ),
'id' => $prefix . '7g',
'type' => 'text',
'size' => 3,
'columns' => 1,
],
[
'name' => __( '14 grams', 'yb' ),
'id' => $prefix . '14_q6tlu8qi78',
'type' => 'text',
'size' => 3,
'columns' => 1,
],
[
'name' => __( '28 grams ', 'yb' ),
'id' => $prefix . '28_ufjrtw5u8oc',
'type' => 'text',
'size' => 3,
'columns' => 1,
],
],
'validation' => [
'rules' => [
$prefix . '2_btw3zbak44j' => [
'number' => true,
],
$prefix . '3' => [
'number' => true,
],
],
],
];
return $meta_boxes;
}
This is one of the code snippets from the plugin I'm trying to recreate:
/**

*
* Adds a product prices metabox to all of the above custom post types
*
* #since 1.0.0
*/

// Add metabox.
add_meta_box(
'wp_dispensary_product_prices',
__( 'Product prices', 'wp-dispensary' ),
'wp_dispensary_product_prices_metabox_content',
'products',
'normal',
'default'
);
}
add_action( 'add_meta_boxes', 'wp_dispensary_product_prices_metabox' );

I am a newbie and I would greatly appreciate any help or a point in the right direction. Thank you.
