Insert record / add record Specify Variable (Optional) -- double check its usage

Insert record / add record Specify Variable (Optional) -- double check its usage

Hi just wanted to double check

For Insert record / add record the Specify Variable (Optional) parameter is only used to return the inserted record ID

Is this correct ? please confirm

Can it return anything else ?

Only thing i could glean was from this post

record_id = insert into contact_us
[
 Added_User = zoho.loginuser
 Address = input.Address
 Date_1 = input.Date_1
 Email = input.Email
 Name = input.Name
 phone = input.phone
];
// record_id contains the ID value of the record inserted to contact_us form
