How do I disable the discard button in javascript?

If also possible the search icon as well.

The highlighted one in this image:

this is my actual code, it works the exact same as the sandbox:

 autocomplete({
            container: "#autocomplete",
            placeholder: "items",
            insights: true,
            openOnFocus: true,
            getSources() {
                return [
                    {
                        sourceId: "simpleItems",
                        getItems({ query }) {
                            const filteredItems = suppliers.filter((item) =>
                                item.name
                                    .toLowerCase()
                                    .startsWith(query.toLowerCase())
                            );
                            return Promise.resolve(filteredItems);
                        },
                        getItemInputValue: ({ item }) => item.name,

                        templates: {
                            item({ item }) {
                                return item.name;
                            },
                        },
                    },
                ];
            },
        });
