Create an optional datatype from a normal one

I want to convert a data type into an optional Data type. I tried the following format:

let newOptionalAdminId = Optional newAdminId

However, I am getting the following error with this

    Data constructor not in scope:
      Optional : TalentId -> Optional TalentId

TalentId is the contract ID for the Template Talent. How can I convert this into an optional datatype?

The constructor for this is called Some, so

let newOptionalAdminId = Some newAdminId

Optional is just the name of the type.
