caseSensitiveSearch={true} not working

[Lakhwinder-Official]

I need to enable case sensitive search in my code but unable to do so.

<Dropdown
displayValue="key"
selectedValues={selectedMembers}
options={users.map((user) => {
return { ...user, key: ${user.login} (${user.email}) };
})}
onSelect={(event) => {
dispatch({ type: "REMOVE", payload: event });
}}
onRemove={(event) =>
dispatch({ type: "ADD", payload: event })
}
showCheckbox
showArrow={true}
caseSensitiveSearch={true}
/>
