How to filter on a Category Archive page

On my archive template page I want to have a Bricks filter. In the archive, which displays all posts in a particular category, the user to be able to filter those items based on an ACF field: {acf_incident_type}.

I have placed a Bricks Select Filter on my page, but cannot see how to set it to filter on the ACF field.

Can anyone help?

Managed to resolve it. It becomes easier to select the Custom ACF field when in Bricks > Settings > Custom fields integration is activated.
