Please help! Create favorites list from database product items (not shop products)

Truthfully try to adapt the wish list sample for this task. The problem is that the information comes from a store and not from a database and I was not able. could someone guide me to create this list of favorites and not die trying?

In fact, I have already created the article page that stores the product and the user id in a database, I only require that with that database a repeater show me those items making the filter on the favorites of each member.

I appreciate the collaboration …

Here,s my code but is broken.

// Import the wix-data module for working with queries.
import wixData from 'wix-data';
// Import the wix-users module for working with users.
import wixUsers from 'wix-users';
// Import the wix-location module for navigating to pages.
import wixLocation from 'wix-location';
//-------------Page Setup-------------//
$w.onReady(async function () {
// Get the current user.
let user = wixUsers.currentUser;
// If the current user is logged in:
if(user.loggedIn)
// Load the user's wishlist using the loadWishlist() function.
return loadWishlist();
// If the current user is not logged in:
// Collapse the wishlist.
$w('#wishlist').collapse();
// Expand the empty whishlist.
$w('#emptyWishlist').expand();
});
// Load and display the current user's wishlist.
async function loadWishlist(){
// Get the current user.
let user = wixUsers.currentUser;
// Query the "favoritos_DB" collection for all wishlist items belonging to the current user.
let wishlistResult = await wixData.query("Favoritos_DB")
.eq("userId", user.id)
.include('product')
.find()
// If any wishlist items were found:
if (wishlistResult.length > 0) {
// Expand the wishlist.
$w("#wishlist").expand();
// Collapse the empty wishlist.
$w("#emptyWishlist").collapse();
// Set the wishlist repeater's data.
$w("#wishlist").data = wishlistResult.items;
// Set the action that occurs when the wishlist repeater items are loaded to the myItemReady() function.
$w('#wishlist').onItemReady(myItemReady);
}
// If no wishlist items were found:
else {
// Collapse the wishlist.
$w("#wishlist").collapse();
// Expand the empty wishlist.
$w("#emptyWishlist").expand();
}
}
// Set up the wishlist repeater items when the repeater's data is loaded.
function myItemReady($w, wishlistItem ){
// Get the wishlist product.
let product = wishlistItem.product;
// Set the repeater's elements using the item data.
$w('#productImage').src = product.logo_emp;
$w('#name')._id = product.nombre_emp;
$w('#price')._id = product.categoria_emp;
// Set the action that occurs when the product image is clicked.
//$w('#productImage').onClick(() => {
// Navigate to the wishlist item's product page.
//wixLocation.to(product.productPageUrl);
//});
// Set the action that occurs when the remove item image is clicked to the removeItem() function.
//$w('#removeItem').onClick(removeItem(wishlistItem._id));
}
// Remove an item from the user's wishlist.
function removeItem(id) {
return async function() {
// Remove the item with the specified ID from the "products-wishlist" collection.
await wixData.remove('Favoritos_DB', id);
// Reload the wishlist to reflect the removed item.
loadWishlist();
}
}
