Hiding a product field by password

I am using WooCommerce for a clients website and have created an extra tab field (using YIKES extra tab plugin) and I would like it only to be visible when someone is a logged in user.

Currently the WooCommerce is set to catalog mode and will be for quite some time.

My clients wants to use the (soon to be hidden) new tab to be notes for his staff that he does not want the public to see

I have WooCommerce Membership plug-in but I think to restrict something there it would mean all viewers would need to register and I don’t want that

so to summarize – I want a field in a Woo Commerce product that can only be viewed if a user is logged in

…. any suggestions?
