Restrict access to menu items on the site using a gasket site

Good afternoon!
There is a personal account of sellers on Wildberries
https://seller.wildberries.ru/

Task: Restrict access to some menu items for some employees. For example, so that they cannot change the prices of goods.

A possible solution: make a proxy server and a gasket site on your domain, through which the employee will connect to an already logged in account, where it will be impossible to click on certain menu items. Login to the account on the https://seller.wildberries.ru/ goes through an SMS code or a code in the application. I dont know how long the quis live.

If it is possible to implement this, we are counting on long-term cooperation, we will need it more than once.
Payment - by agreement, depending on the proposed solution
