A new bookmark can be added when we try to edit a report in Power BI. Is there a way we can add and update/delete it when user opens the report in view mode?
Currently, it is not possible for someone without editing permissions to create new bookmarks.
However, personalized bookmarks are a popular idea that Microsoft has stated they've started working on (5/21/2018), so I'd expect it to be released in one of the upcoming monthly updates.
