Can Data Bucket Shared With Other People?

For example share link data bucket like dashboard org something?

Yes sure, for buckets you can define a token and provide access to a 3rd party apps by the RestAPI feature.

The dashboard also can be shared to be consulted by a browser.

Hope this helps.

Sharing read access is not problem. Sharing write rights is the ticket to a huge mess.

In medium instances it is possible to create projects and members with fine grained permissions to see bucket data, export data, export lists, clear data, etc.
