When I review other teammate's LucidChart file I do not want to change it by mistake, so I hope I can set the chart as readonly, how to do it ?
How to set a chart as readonly ?

Hey
As an alternative, you could create a duplicate of the document. This would allow you to be the owner of the document and make changes without effecting the original. To create a duplicate, navigate to file > duplicate.
Hope this helps!
