Context:
The backend currently doesn't support CSV exports on multi measure reports (multiple view properties, multiple aggregations, multiple user task duration times) and we decided to not include support for it in Optimize 3.4.0.
AT:
- once a report becomes a multi-measure report due to multiple view properties, multiple aggregations or multiple user task duration times being configured the CSV export button should be hidden
a tool-tip on the button indicates why it is disabled
