Wikipedia Page Update and Cleanup

I'm seeking an experienced Wikipedia editor to update and clean up a specific Wikipedia page. The focus will be on correcting vandalism and updating the background and history sections using official reports as references.

Key Requirements:
- Vandalism removal
- Update background/history with accuracy
- Reference official reports for updates
- Ensure compliance with Wikipedia's content guidelines

I need to understand the policy what the freelancer can and can not do for me.
Ideally looking for experienced editor that can edits the page themselves, with help from me giving them facts contexts.
