SQL autojoin to ORM Cake3

Hi, I have this SQL a need to transform to ORM. I I appreciate any approach


LOGS
id - group_id - data
1        1      'Lorem ipsum 1'
2        1      'Lorem ipsum 2'
3        2      'Lorem ipsum 3'


SQL return the latest record in your group:
id - group_id - data
2        1      'Lorem ipsum 2'
3        2      'Lorem ipsum 3'

SELECT logs.id,logs.group_id,logs.data
FROM logs
LEFT JOIN logs AS latest
ON
(logs.group_id = latest.group_id AND logs.id < latest.id)
WHERE latest
.id IS NULL
ORDER BY logs
.id DESC
