Group by inspection not working

I'd expect the group by inspection to activate when I write the following:

select
  partner_id
, count(*)
from t_cn_event_basis_agg;

However, nothing happens.

I'm on DataGrip 2018.1 with Exasol as the database.

Is there any way to activate the inspection?

Also, it would be nice if the inspection could use the Exasol specific function to group by column position, e.g.:

select
  partner_id
, count(*)
from t_cn_event_basis_agg
group by 1;
