   not great practice in react but this could be a solution, less involved than the above suggestion.
   
   ```
   import { useEffect, useRef } from 'react';
   
   const useEffectOnce = (effect: () => void) => {
     const hasRun = useRef(false);
   
     useEffect(() => {
       if (!hasRun.current) {
         hasRun.current = true;
         return effect();
       }
     }, [effect]);
   };
   
   export default useEffectOnce;
   
   ```
   
   
   ```
   useEffectOnce(() => {
     embedDashboard({
       id: "superset-dashboard-id", // given by the Superset embedding UI
       supersetDomain: "https://superset-bas-dev.bridge.propelmarine.com",
       mountPoint: document.getElementById("superset-container") as HTMLElement, // any html element that can contain an iframe
       fetchGuestToken: async () => {
         console.log("fetchGuestToken");
         return guestToken;
       },
       dashboardUiConfig: {
         // dashboard UI config: hideTitle, hideTab, hideChartControls, filters.visible, filters.expanded (optional)
         hideTitle: true,
         filters: {
           expanded: false,
         },
       },
     });
   });
   ```
