I want to find all logs between two dates however this search does not work

@Timestamp > DateTime(concat('2024-06-19 19:00', 'Z')) and @Timestamp < DateTime(concat('2024-06-19 19:20', 'Z'))

if I use only this query I see results

@Timestamp > DateTime(concat('2024-06-19 19:00', 'Z'))

How do I combine multiple conditions in the search?
