Currently, odoo not provide access to the sales team to quotation. Using this module your sales team members can access the sale order/quotation. This module automatically adds sales team members to the follower's list. All followers can see the sales order. when the salesperson login they can see all the sales orders/quotations. This will be applicable from new quotation/sale orders as we are adding team members as followers on create of records. We have applied this rule in own for the user who has their own documents group. so this rule will be not applied to other groups.
