Attribute types: User
User attribute type lets you set email address as a value in the table.
When setting the type, you can choose whether you allow only registered users (who belong to the organization) or any valid email address.
If the address belongs to an existing user and they registered with a name (e.g. they are signing in via their Google account and have a name set up there), then their name will be displayed if the “Display user name/email” option is turned on. Otherwise, their email address will be displayed.
