Hi there Dinnemidi Ananda Kumar
that's a good question and thanks for using QandA platform
To start, make sure your JSON data in Cosmos DB includes role information and reporting structures.
Now, Azure RBAC comes into play. It's imp for managing access to Azure services, including Cosmos DB. Set up roles and permissions here according to your organizational structure.
Next, implement custom access control logic within your application. For Employees, they should only view their own data. Assistant Managers should access their data and data of those they manage. Managers should have access to their own data, plus data of their direct reports and their reports' subordinates. As for CTO and CEO, they get access to everything.
let me drop you the needed documentation links below and go through them for more info
