Add the explicit return type to typeConfirmation.

The TypeScript guidance applies to this .tsx file and requires explicit return types for functions. The inference guidance does not define an exception. Add : Promise<void>.

Suggested fix 
-async function typeConfirmation(user: ReturnType<typeof userEvent.setup>) {
+async function typeConfirmation(user: ReturnType<typeof userEvent.setup>): Promise<void> {
📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Suggested change
async function typeConfirmation(user: ReturnType<typeof userEvent.setup>) {
async function typeConfirmation(user: ReturnType<typeof userEvent.setup>): Promise<void> {

Add the explicit Promise<void> return type to the async typeConfirmation
function, keeping its existing parameter type and behavior unchanged.
