You are absolutely right.
Most temporary measures under the CUEAT programme ended on March 31, 2024. Specifically, this policy expired on March 31, 2024

There are some exceptions for those who was approved on or after February 4, 2024, see
https://www.canada.ca/en/immigratio...kraine-measures/ukraine-open-work-permit.html
All currently available measures are listed here
https://www.canada.ca/en/immigratio...rvices/immigrate-canada/ukraine-measures.html. For example, "Your CUAET application was approved before February 4, 2024" -> "You arrived in Canada on or before March 31, 2024" ->
you must apply through the regular process (under regular program requirements). So, no special measures in that case. You have to apply like everybody else under the regular process.
