How do I set up an approval process for new users joining my SharePoint site?

1. Ensure that the right authentication and authorization controls are in place to grant permissions to new users.

2. Set up a workflow to define the specific approval steps that need to take place when adding a new user.

3. Make sure the appropriate team members/ individuals are set as approvers for the approval process.

4. Configure email notifications to be sent to approvers and new users when approvals have been actioned.

5. Define a specific set of SharePoint permissions that are granted or revoked at each stage of the approval process.

6. Create reporting for tracking user access requests and managing the approval process.
