inventoryLevelItems example for GraphQL

[czupet]

There is the listProducts example for GraphQL and I got it to work in my application, but now I need help with InventoryLevel.
Do you have an example of how to retrieve inventoryLevel?

Here's my code, but I am getting error (undefinedField: Field 'inventoryLevels' doesn't exist on type 'QueryRoot')

var graphRequest = new GraphRequest
{
Query = """
query inventoryLevelItems($limit: Int!, $id: ID!) {
inventoryLevels(first: $limit, id: $id) {
id
inventoryLevels(first: 10) {
edges {
node {
id
location {
id
name
}
quantities(names: ["available"]) {
name
quantity
}
}
}
}
}
}
""",
Variables = new Dictionary<string, object>
{
{"limit", 10},
{"id", itemId}
}
};

public record ListInventoryLevelItemsResult
{
[StringSyntax("GraphQL")]

public required InventoryLevelConnection InventoryLevelItems { get; set; } = new();

}
