Add new Input Field on Seller Registration Page

I want to add new input field (Agent ID) upon seller registration

I have written the code which is here below and I added it on the dokan lite plugin file – wp-content/plugins/dokan/templates/global/seller-registration-form.php but it isn’t displaying on the frontend

Here is the code I added

<p class=”form-row form-group form-row-wide”>
<label for=”agent-id”><?php esc_html e( ‘Agent ID’, ‘dokan-lite’ ); ?><span class=”required”>*</span></label>
<input type=”text” class=”input-text form-control” name=”agent_id” id=”agent-id” value=”<?php if ( ! empty( $_POST[‘agent_id’] ) ) echo esc_attr($_POST[‘agent_id’]); ?>” required=”required” />
</p>
What do i need to do for it to be added and display properly.

Thanks
