Connector settings
One tab per connector. Under "who may write", each tool lists the people allowed to use it, or has no extra limit from this list. A tool that is not listed follows the Default row. This list never grants anything: each person's own Servicely token is still the real limit, and this is only an extra guard rail on top of it. Saving needs write access to the storage container; if you do not have it, Azure refuses the save.
