Order Product Samples for WooCommerce

I am using the Order Product Samples plugin on my WooCommerce website.

At the moment, the plugin allows sample buttons to be shown to guest users when “Enable Rule For Guest Users” is enabled, but customers are still required to log in or register before they can purchase samples.

The message shown is:

Account Required
Only registered users can purchase sample products. Please create an account to proceed.

I would like to request a feature that allows guest users to purchase sample products without needing to create an account, as long as WooCommerce guest checkout is enabled.

Ideally, there would be a setting such as:

Allow guest checkout for sample products
Yes / No

This would be very useful because many customers want to order samples quickly before committing to an order, and forcing account registration at this stage can create friction and reduce conversions.

My WooCommerce settings already allow guest checkout, so it would be helpful if the sample plugin could follow the normal WooCommerce checkout rules.

Please let me know if this is already possible, or if it can be considered for a future update.
