memberships property

List<Membership>? memberships

The Google Chat users or groups to invite to join the space.

Omit the calling user, as they are added automatically. The set currently allows up to 49 memberships (in addition to the caller). For human membership, the Membership.member field must contain a user with name populated (format: users/{user}) and type set to User.Type.HUMAN. You can only add human users when setting up a space (adding Chat apps is only supported for direct message setup with the calling app). You can also add members using the user's email as an alias for {user}. For example, the user.name can be users/[e-mail]. To invite Gmail users or users from external Google Workspace domains, user's email must be used for {user}. For Google group membership, the Membership.group_member field must contain a group with name populated (format groups/{group}). You can only add Google groups when setting Space.spaceType to SPACE. Optional when setting Space.spaceType to SPACE. Required when setting Space.spaceType to GROUP_CHAT, along with at least two memberships. Required when setting Space.spaceType to DIRECT_MESSAGE with a human user, along with exactly one membership. Must be empty when creating a 1:1 conversation between a human and the calling Chat app (when setting Space.spaceType to DIRECT_MESSAGE and Space.singleUserBotDm to true).

Optional.
