A user in Google Chat. When returned as an output from a request, if your Chat app authenticates as a user, the output for a User resource only populates the user's name and type.
Format: users/{user}. users/app can be used as an alias for the calling app bot user.
For human users, {user} is the same user identifier as:
the id for the Person in the People API. For example, users/123456789 in Chat API represents the same person as the 123456789 Person profile ID in People API.
the user's email address can be used as an alias for {user} in API requests. For example, if the People API Person profile ID for user@example.com is 123456789, you can use users/user@example.com as an alias to reference users/123456789. Only the canonical resource name (for example users/123456789) will be returned from the API.
