I need to use Jira Automation and run a rule, but only on issues that do not yet have "depends on" links.
I tried various combinations of the settings for Condition, and looked for some systematic documentation on this, to no avail.
Can the following (which doesn't work) be tweaked so as to only run the rules on issues that do not yet have any "depends on" link?

Or should something completely different be done?
Any help would be much appreciated (pointers to any kind of clear and systematic documentation, etc.)!
