Oldest detection date of all cves summarized under one fix per asset

Hi together,

we are currently using below query to create report that summarizes Cves under fixes per asset with some additional information.

However one important part is missing. We want also the oldest detection date of all cves which are summarized under one fix in a seperate column.
In other words, this is the same as when the fix could have been applied to the asset for the first time.

Do you have any idea how we can achieve this?

thank you in advance
and kind regards

WITH region_tags
AS (SELECT dta.asset_id,
dt.tag_name AS region

JOIN dim_tag_asset dta
ON dt.tag_id = dta.tag_id
WHERE dt.tag_type = ‘LOCATION’
AND dt.tag_name = ‘###’
),

dt.tag_name AS country
FROM dim_tag dt

ON dt.tag_id = dta.tag_id

AND dt.tag_name <> ‘###’
)
)

GROUP BY ds.fix,
ds.summary,
rt.region,
da.host_name,
dos.description,
da.ip_address,
da.last_assessed_for_vulnerabilities

Or to simplify the question how to get thoose two columns marked in red via a query?
for reference this are vulnerability instances of a specific vulnerability on an asset.
