Need help writing an if statement in idocScript for a rule

Good Day,

A user requires certain documents to be only be visible to a specific role.

For example

A document is checked in and it has a document type of 1234 then the role applied is SECURE_ROLE

I was trying to write a condition in the checkin rule for the clbrarolelist metadata field or if that's not correct then in the Document Type metadata field in the derived value field.

I need help rewriting the following into idoc script.

If xcig_doctype is '1223' or '12325' or '1452'

then xclbraRoleList is SECURE_ROLE

And also am I writing it in the correct location?
