Firstly, you need to assign permissions for different roles.

Example with Airtable

  1. Create 3 tables named Roles, Home Tab, Chat Tab
  2. Roles tab contains two Columns named Role Title and Permitted Areas
  3. When user signed up, store his role on database
  4. When user sign in, get values from Roles tab & compare permissions for his role
  5. Show him contents only from the Tables stored in Permitted Areas
