For pre-configured tools, it is not necessary to enter a shared secret here, as the shared secret will be
provided as part of the configuration process.

This field should be entered if creating a link to a tool provider which is not already configured.
If the tool provider is to be used more than once in this course, adding a course tool configuration is a good idea.

The shared secret can be thought of as a password used to authenticate access to the tool. It should be provided
along with the consumer key from the tool provider.

Tools which do not require secure communication from Moodle and do not provide additional services (such as grade reporting)
may not require a shared secret.
