In the "Team management" section for your company on DeepStream, you can see all users associated with your respective company. Additionally, each user’s level of company-wide permissions are fully visible to you (note that these are different from Request specific permissions). Users who have the "Edit team members" permissions enabled, have control over all users joining and can remove users from the company, along with editing their permissions. They are able to give access to users who are advising the company (e.g. lawyers or consultants) to increase the information flow across the team and increase collaboration. You can also add new team members by sending an invitation to their emails asking them to join.
In the "Team management" section, the company-wide permissions for each user can be set. There are currently four different types of user permissions: Edit team members - Can control what permissions each user has on DeepStream, along with managing all joining or removal of team members. Edit company profile - Can build and modify the company profile including company information, descriptions and products/services. Send Requests - Can create new Requests and send them to suppliers once ready. Receive Requests - Can receive new Requests and respond to buyers once ready to bid.
New user requests appear under the "Invitation" tab in the "Team management" section, where you can accept or reject them, as long as you have "Edit team members" permission.
