Restrict cost field to user

Hi,

First of all, thank for your dev and plugin. We plan to use it after that we find a solution to the following problem :

We have employes that use the woocommerce app and have access to the product edition page. We want to restrict the visualization of the field cost to protect our business but I couln’t find a way to restrict this specific field for a group of user (not admin). How can we do ?

Thank in advance,

Regards,

Adrien
