db_snow_mask apply masking policy problem

I have created masking policy named custemail through dbt_snow_mask.

model.yml

version: 2

models:

  • name: customers_raw

    description: Staged customer data from order management system (OMS), with minor row-level transformations.

    columns:

    • name: email

      meta:

      masking_policy: custemail

dbt_project.yml

on-run-end:

  • “{{ dbt_snow_mask.apply_masking_policy(‘models’) }}”

But not able to apply it in snowflake table. Please help.
