Employees with different permissions view different products

I have been in contact with Dolibarr for a month, very good ERP products that meet our requirements.
Even if there are some special requirements, solutions can be found in the forum.
I also have a problem with employees with different permissions viewing different products.
for example I don’t want sales people looking at products that aren’t for sale. I know that these products will not be displayed when creating a quote, but they will be fully displayed in the product module list.
In the permissions of the product module, only read products, no read permissions for specific products.
What am I supposed to do?
