Currently, the conditional visibility expressions only apply to the current feature that is being created or edited. In the future, this might change if we add support for Arcade Feature Sets in the context of the form.
If you want to reference other fields on the current feature you can use logical AND (&&) and/or OR (||) operators to combine conditions.
(IndexOf(["Not Accessible", "Not In Field"], DomainName($feature,"Inspection_Status")) >= 0) || ($feature.some_field == "test")
Does that answer your question?
