File Upload Field not using React Component

Hello, good day.

I am building a custom app and would need to use the file upload field. However, all I can find on Zendesk Garden is the file upload React Component. The app is not built on React, so using the React Component is not an option. I tried using the HTML file upload field but it's not working. When I tried clicking Choose File button, it doesn't do anything.

<div class="c-txt">
        <label for="incidentAttachment">Incident Attachment</label><br />
        <input id="incidentAttachment" type="file" />
</div>

Is there a way to have the file upload field without using the React Component?

I hope someone can help me.

Thank you in advance,
Benessa
