How many websites under localhost can each license key use? Each website is a vi

I’m researching how to use the Woodmart theme for my WordPress website, and I’m researching it on a localhost machine using the Xampp software. I have purchased the License key of the theme on Themeforest, and I have a question like this, for 1 license key, how many websites can I create locally via virtual domain? With each license key, how many virtual domains can be used under localhost with each domain being another website (also under localhost)? Is there any quantity limit for this?
