How to give more than one team access to the same project
If you've set up your teams like security groups, in that you have one team for your test leads and another for team members, with each team having multiple permissions, you may want to assign multiple teams to a project.
Step 1: Navigate to the project.
From the Organizations page, click on the organization that the project is in and then click Projects.
You'll then see a list of the projects in that organization.
Step 2. Select the checkbox to the left of the project you want to assign to a team. Then click Add to a team.
Step 3. Select a team from the dropdown menu and click Add Projects to Team.
Step 4. Do this for as many teams as you would like to add to the project.
