Using Bigquery custom functions in dbt

[ma1069]

Hello,
I'm trying to materialize in DBT cloud a query that is currently running on Google Bigquery, containing a javascript function definition at the beginning.

to clarify, between the
{{ config(materialize='table') }}
and the
SELECT ...
I have a piece of code in the form of
CREATE TEMPORARY FUNCTION match(str1 STRING, str2 STRING) ...

This query works in the preview and works perfectly when launched directly in google bigquery, but it causes an error when launching dbt run.
The issue is:
Syntax error: Expected "(" or keyword SELECT or keyword WITH but got keyword CREATE at [...]

Is there a way to tell dbt to ignore a portion of the script and leave it as is in the compiled query without trying to parse it? I already tried with jinja {{ raw }} statement but that didn't work out

Thank you,
Matteo
