in layout.tsx file

 return (
    <div >

           <NavBar/>
           {children}
           <Footer/>
    </div>
  );

in NavBar component i get data with nextjs ServerActions,
i want to revalidate NavBar component with on-demand revalidation not like

export const revalidate = 3600 // invalidate every hour

also only the navbar component should revalidate. not the all pages like "revalidatePath(/,"layout")"
