Suggestion not showing up for input

I am trying to learn react by practising a simple problem. I followed the below youtube tutorial https://www.youtube.com/watch?v=AsvybgZTryo&list=PLKhlp2qtUcSZiWKJTi5-5r6IRdHhxP9ZU&index=17

but when I search for an item the suggestions are not coming, I debugged by putting console, still console not printing

can you let me know what is the issue, providing the code snippet and stackblitz below

<ul className="suggestions-list">
{suggestions?.users?.map((user, index) => {
console.log('slectedUserSet --->', slectedUserSet);
return slectedUserSet.has(user.email) ? (
// current user which we selected
<li key={user.email} onClick={() => handleSelectUser(user)}>
<img
src={user.image}
alt={`${user.firstName} ${user.lastName}`}
/>
<span>
${user.firstName} ${user.lastName}
</span>
</li>
) : (
<></>
);
})}
</ul>
