Shared Bucket - External Bucket

Each user can only see their created buckets. When shared, the bucket receives extended rights for other users and is only verified when it is directly queried. Therefore, you need to know the name of the bucket and go directly to it, and then after verifying the rights, it will be made available to you.

In case of connection to an external bucket, it must still be in “Advanced”

click on “Directory” and fill in the name of the bucket in the “Remote directory” column.

Then just OK and log in.
