Dbt-trino 1.9 Microbatch

[atomsis]

Hello everyone (and first of all, dear dbt-trino developers <3)
I saw that you released version 1.9 on December 20 and Microbath support appeared there - but no matter where I looked (dbt documentation or something similar (which I just did not look for)), there is no mention or instructions on how to use Microbatch in dbt-trino.
I tried to do similar to what is on the conditional databricks or databricks: incremental_strategy='microbatch',
unique_key='sales_id', ## required for dbt-postgres
event_time='transaction_date',
begin='2023-01-01',
batch_size='day'
but it doesn't seem to be working.
Please clarify the situation - is there something I don't understand? Is there documentation about dbt-trino 1.9 Microbath somewhere?
