ok so im wanting to know if it is possible to hide a specific product or products so it cant be seen on my site but still allow anyone with a direct link to it to still be abler to add to cart and checkout with it

the reason is this, i have a product that is to pay for booking a market pitch however i don't want just anyone to be able to see it, only those who have filled out my booking form via email and i have approved to attend the event and so have received the link to the product page

i previously did this by default on my old website that was set up through weebly and it had 3 statuses for products active, hidden and disabled
active - everyone can see and buy
hidden - didnt show up on the site in search results or in categories but a direct link allowed you to view and add to cart
disabled - self explanatory

is this possible for a person with only novice coding ability but can follow instructions well
