I will import your component, and help to handle it

let preloaders = [];
/**
 * adds a precondition before resolving any imported object
 */
export const addPreloader = (preloader) => {
    preloaders.push(preloader);
    return () => {
        preloaders = preloaders.filter((p) => p !== preloader);
    };
};
export const getPreloaders = () => preloaders.map((preloader) => preloader());
