REACT_APP_POLICY_CONFIG

Depending on the value of REACT_APP_POLICY_CONFIG in .env, you can customize which roles should be displayed in center stage and which roles should be display in side pane.

The value of REACT_APP_POLICY_CONFIG should be a JSON stringified object of the structure:

type HMSRoleName = string;

/**
 * undefined means none
 * empty array [] for all roles
 */
interface RoleConfig {
  center?: HMSRoleName[];
  sidepane?: HMSRoleName[];
  selfRoleChangeTo?: HMSRoleName[];
  remoteRoleChangeFor?: HMSRoleName[];
}

interface PolicyConfig {
  [role: string]: RoleConfig;
}

Example: REACT_APP_POLICY_CONFIG = "{"trainer":{"center": ["student"],"sidepane":["trainer"]}}"

It is used in the app as:

const envPolicyConfig = JSON.parse(process.env.REACT_APP_POLICY_CONFIG || "{}");
