User and organization data 
vimOS.sessionContext provides both information about the Vim Connect user and methods for interacting with this data. This includes details collected during the User and/or Clinic onboarding process to Vim Connect, with the exception of the EHR username.
ts
interface SessionContext {
  sessionId: string;
  user: User;
  organization: Organization;
  ehrType?: string;
  getIdToken: Promise<GetIdTokenResponse>;
}WARNING
Your application will only receive information for the entities it declared read access for under the 'User Details' section in the Developer Console; Entities for which read access wasn't declared will always be undefined.
sessionId 
vimOS.sessionContext.sessionId is a unique identifier that represents a unique user session in Vim Hub. It is generated when Vim Hub loads and is refreshed each time there is a new Vim Hub session.
User 
vimOS.sessionContext.user holds information about the user that is logged in to the EHR and Vim:
ts
export interface user {
  identifiers?: {
    vimUserID: string;
    ehrUsername: string;
    npi: string;
    roles?: string[];
  };
  demographics?: {
    firstName: string;
    lastName: string;
  };
  contactInfo?: {
    email: string;
  };
}ts
const user = {
  identifiers: {
    vimUserID: 203948209842098402,
    ehrUsername: 'john9328',
    npi: '123456',
    roles: ['Medical Doctor'],
  },
  demographics: {
    firstName: 'John',
    lastName: 'Pisoto',
  },
  contactInfo: {
    email: '[email protected]',
  },
};Organization 
vimOS.sessionContext.organization contains details about the organization to which the currently logged-in user belongs.
ts
export interface Organization {
  identifiers?: {
    id: number;
    name: string;
    tin: string;
  };
}ts
const organization = {
  identifiers: {
    id: 1923,
    name: 'Medical group associates',
    tin: ['123456'],
  },
};ehrType 
vimOS.sessionContext.ehrType holds the name of the EHR the user is currently using.
getIdToken 
ts
export interface GetIdTokenResponse {
  idToken: string;
}vimOS.sessionContext.getIdToken() returns the current session ID token, which can be used for Single Sign-On (SSO) flows as described in the Application SSO section.
