HELLO Odoo V17, we have vendor users. Each vendor has their own clients, and they should only see their own clients' data. Currently, from the CRM module and from SALES/ORDERS/CUSTOMERS, they can see all users' clients and suppliers. How can I limit that access?   
When registering a new client in the Sales and Purchases tab, in the Salesperson field, select the assigned salesperson to restrict access. However, they can still see the contacts of other sales users.

Finally, as an example, I have 100 clients registered.

Only user 1 (should display 50 clients)
user 2 (should display 40 clients)
user 3 (should display 10 clients)
But currently, from the aforementioned modules, all users see everyone's clients. Thank you for your time and response to my question.
