Questions on MS purview workflow and glossary term

1. Could we see the change history inside glossary term?

2. Could we create specific role in purview like remove the right to import glossary term inside "Data Curator"? since the Import function is too strong, will overwrite the current term and could not add expert or steward's approval......

3. Could we have any right that could view all workflow run history instead of only workflow creator could view?

4. After approval in workflow, the glossary term will be "last updated by Service Admin" instead of requestor (The one who really changed the glossary term) seems not make sense...... Could we change it in workflow to show last updated by requestor?

5. While a glossary term is waiting for approval, if there are any new update in the glossary term, it will overwrite the existing change (which is pending for approval). Could we freeze the glossary term or change the status to "draft" while the glossary term is pending for approval?
